The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration files inside the chroot.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has openssl098e packages installed that are affected by multiple vulnerabilities:

  - OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d     allows remote attackers to cause a denial of service     (infinite loop and memory consumption) via malformed     ASN.1 structures that trigger an improperly handled     error condition. (CVE-2006-2937)

  - OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions allows attackers to cause a denial of     service (CPU consumption) via parasitic public keys with     large (1) public exponent or (2) public modulus     values in X.509 certificates that require extra time to     process when using RSA signature verification.
    (CVE-2006-2940)

  - Buffer overflow in the SSL_get_shared_ciphers function     in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions has unspecified impact and remote     attack vectors involving a long list of ciphers.
    (CVE-2006-3738)

  - OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8     before 0.9.8c, when using an RSA key with exponent 3,     removes PKCS-1 padding before generating a hash, which     allows remote attackers to forge a PKCS #1 v1.5     signature that is signed by that RSA key and prevents     OpenSSL from correctly verifying X.509 and other     certificates that use PKCS #1. (CVE-2006-4339)

  - The get_server_hello function in the SSLv2 client code     in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions allows remote servers to cause a denial     of service (client crash) via unknown vectors that     trigger a null pointer dereference. (CVE-2006-4343)

  - The BN_from_montgomery function in crypto/bn/bn_mont.c     in OpenSSL 0.9.8e and earlier does not properly perform     Montgomery multiplication, which might allow local users     to conduct a side-channel attack and retrieve RSA     private keys. (CVE-2007-3108)

  - Off-by-one error in the DTLS implementation in OpenSSL     0.9.8 before 0.9.8f allows remote attackers to execute     arbitrary code via unspecified vectors. (CVE-2007-4995)

  - Off-by-one error in the SSL_get_shared_ciphers function     in OpenSSL 0.9.7 up to 0.9.7l, and 0.9.8 up to 0.9.8f,     might allow remote attackers to execute arbitrary code     via a crafted packet that triggers a one-byte buffer     underflow. NOTE: this issue was introduced as a result     of a fix for CVE-2006-3738. As of 20071012, it is     unknown whether code execution is possible.
    (CVE-2007-5135)

  - OpenSSL 0.9.8i and earlier does not properly check the     return value from the EVP_VerifyFinal function, which     allows remote attackers to bypass validation of the     certificate chain via a malformed SSL/TLS signature for     DSA and ECDSA keys. (CVE-2008-5077)

  - The ASN1_STRING_print_ex function in OpenSSL before     0.9.8k allows remote attackers to cause a denial of     service (invalid memory access and application crash)     via vectors that trigger printing of a (1) BMPString or     (2) UniversalString with an invalid encoded length.
    (CVE-2009-0590)

  - The dtls1_buffer_record function in ssl/d1_pkt.c in     OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote     attackers to cause a denial of service (memory     consumption) via a large series of future epoch DTLS     records that are buffered in a queue, aka DTLS record     buffer limitation bug. (CVE-2009-1377)

  - Multiple memory leaks in the     dtls1_process_out_of_seq_message function in     ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8     versions allow remote attackers to cause a denial of     service (memory consumption) via DTLS records that (1)     are duplicates or (2) have sequence numbers much greater     than current sequence numbers, aka DTLS fragment     handling memory leak. (CVE-2009-1378)

  - Use-after-free vulnerability in the     dtls1_retrieve_buffered_fragment function in     ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote     attackers to cause a denial of service (openssl s_client     crash) and possibly have unspecified other impact via a     DTLS packet, as demonstrated by a packet from a server     that uses a crafted server certificate. (CVE-2009-1379)

  - ssl/s3_pkt.c in OpenSSL before 0.9.8i allows remote     attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via a DTLS     ChangeCipherSpec packet that occurs before ClientHello.
    (CVE-2009-1386)

  - The dtls1_retrieve_buffered_fragment function in     ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows     remote attackers to cause a denial of service (NULL     pointer dereference and daemon crash) via an out-of-     sequence DTLS handshake message, related to a fragment     bug. (CVE-2009-1387)

  - The Network Security Services (NSS) library before     3.12.3, as used in Firefox; GnuTLS before 2.6.4 and     2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products     support MD2 with X.509 certificates, which might allow     remote attackers to spoof certificates by using MD2     design flaws to generate a hash collision in less than     brute-force time. NOTE: the scope of this issue is     currently limited because the amount of computation     required is still large. (CVE-2009-2409)

  - OpenSSL before 0.9.8m does not check for a NULL return     value from bn_wexpand function calls in (1)     crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3)     crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which     has unspecified impact and context-dependent attack     vectors. (CVE-2009-3245)

  - The TLS protocol, and the SSL protocol 3.0 and possibly     earlier, as used in Microsoft Internet Information     Services (IIS) 7.0, mod_ssl in the Apache HTTP Server     2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5     and earlier, Mozilla Network Security Services (NSS)     3.12.4 and earlier, multiple Cisco products, and other     products, does not properly associate renegotiation     handshakes with an existing connection, which allows     man-in-the-middle attackers to insert data into HTTPS     sessions, and possibly other types of sessions protected     by TLS or SSL, by sending an unauthenticated request     that is processed retroactively by a server in a post-     renegotiation context, related to a plaintext     injection attack, aka the Project Mogul issue.
    (CVE-2009-3555)

  - Memory leak in the zlib_stateful_finish function in     crypto/comp/c_zlib.c in OpenSSL 0.9.8l and earlier and     1.0.0 Beta through Beta 4 allows remote attackers to     cause a denial of service (memory consumption) via     vectors that trigger incorrect calls to the     CRYPTO_cleanup_all_ex_data function, as demonstrated by     use of SSLv3 and PHP with the Apache HTTP Server, a     related issue to CVE-2008-1678. (CVE-2009-4355)

  - The kssl_keytab_is_available function in ssl/kssl.c in     OpenSSL before 0.9.8n, when Kerberos is enabled but     Kerberos configuration files cannot be opened, does not     check a certain return value, which allows remote     attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via SSL cipher     negotiation, as demonstrated by a chroot installation of     Dovecot or stunnel without Kerberos configuration files     inside the chroot. (CVE-2010-0433)

  - The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c     in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1     before 1.0.1a does not properly interpret integer data,     which allows remote attackers to conduct buffer overflow     attacks, and cause a denial of service (memory     corruption) or possibly have unspecified other impact,     via crafted DER data, as demonstrated by an X.509     certificate or an RSA public key. (CVE-2012-2110)

  - The TLS protocol 1.2 and earlier, as used in Mozilla     Firefox, Google Chrome, Qt, and other products, can     encrypt compressed data without properly obfuscating the     length of the unencrypted data, which allows man-in-the-     middle attackers to obtain plaintext HTTP headers by     observing length differences during a series of guesses     in which a string in an HTTP request potentially matches     an unknown string in an HTTP header, aka a CRIME     attack. (CVE-2012-4929)

  - OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1     before 1.0.1d does not properly perform signature     verification for OCSP responses, which allows remote     OCSP servers to cause a denial of service (NULL pointer     dereference and application crash) via an invalid key.
    (CVE-2013-0166)

  - The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0     and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and     other products, do not properly consider timing side-     channel attacks on a MAC check requirement during the     processing of malformed CBC padding, which allows remote     attackers to conduct distinguishing attacks and     plaintext-recovery attacks via statistical analysis of     timing data for crafted packets, aka the Lucky     Thirteen issue. (CVE-2013-0169)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the openssl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a     memory-cache side-channel attack on ECDSA signatures     that can be mitigated through the use of blinding     during the signing process in the _gcry_ecc_ecdsa_sign     function in cipher/ecc-ecdsa.c, aka the Return Of the     Hidden Number Problem or ROHNP. To discover an ECDSA     key, the attacker needs access to either the local     machine or a different virtual machine on the same     physical host.(CVE-2018-0495)

  - OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1     before 1.0.1d does not properly perform signature     verification for OCSP responses, which allows remote     OCSP servers to cause a denial of service (NULL pointer     dereference and application crash) via an invalid     key.(CVE-2013-0166)

  - OpenSSL 1.0.2 (starting from version 1.0.2b) introduced     an 'error state' mechanism. The intent was that if a     fatal error occurred during a handshake then OpenSSL     would move into the error state and would immediately     fail if you attempted to continue the handshake. This     works as designed for the explicit handshake functions     (SSL_do_handshake(), SSL_accept() and SSL_connect()),     however due to a bug it does not work correctly if     SSL_read() or SSL_write() is called directly. In that     scenario, if the handshake fails then a fatal error     will be returned in the initial function call. If     SSL_read()/SSL_write() is subsequently called by the     application for the same SSL object then it will     succeed and the data is passed without being     decrypted/encrypted directly from the SSL/TLS record     layer. In order to exploit this issue an application     bug would have to be present that resulted in a call to     SSL_read()/SSL_write() being issued after having     already received a fatal error. OpenSSL version     1.0.2b-1.0.2m are affected. Fixed in OpenSSL 1.0.2n.
    OpenSSL 1.1.0 is not affected.(CVE-2017-3737)

  - An out-of-bounds write flaw was found in the way     OpenSSL reused certain ASN.1 structures. A remote     attacker could possibly use a specially crafted ASN.1     structure that, when parsed by an application, would     cause that application to crash.(CVE-2015-0287)

  - It was found that OpenSSL clients and servers could be     forced, via a specially crafted handshake packet, to     use weak keying material for communication. A     man-in-the-middle attacker could use this flaw to     decrypt and modify traffic between a client and a     server.(CVE-2014-0224)

  - There is an overflow bug in the AVX2 Montgomery     multiplication procedure used in exponentiation with     1024-bit moduli. No EC algorithms are affected.
    Analysis suggests that attacks against RSA and DSA as a     result of this defect would be very difficult to     perform and are not believed likely. Attacks against     DH1024 are considered just feasible, because most of     the work necessary to deduce information about a     private key may be performed offline. The amount of     resources required for such an attack would be     significant. However, for an attack on TLS to be     meaningful, the server would have to share the DH1024     private key among multiple clients, which is no longer     an option since CVE-2016-0701. This only affects     processors that support the AVX2 but not ADX extensions     like Intel Haswell (4th generation). Note: The impact     from this issue is similar to CVE-2017-3736,     CVE-2017-3732 and CVE-2015-3193. OpenSSL version     1.0.2-1.0.2m and 1.1.0-1.1.0g are affected. Fixed in     OpenSSL 1.0.2n. Due to the low severity of this issue     we are not issuing a new release of OpenSSL 1.1.0 at     this time. The fix will be included in OpenSSL 1.1.0h     when it becomes available. The fix is also available in     commit e502cc86d in the OpenSSL git     repository.(CVE-2017-3738)

  - The ssl3_send_client_key_exchange function in s3_clnt.c     in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and     1.0.1 before 1.0.1h, when an anonymous ECDH cipher     suite is used, allows remote attackers to cause a     denial of service (NULL pointer dereference and client     crash) by triggering a NULL certificate     value.(CVE-2014-3470)

  - It was discovered that the SSLv2 protocol     implementation in OpenSSL did not properly implement     the Bleichenbacher protection for export cipher suites.
    An attacker could use a SSLv2 server using OpenSSL as a     Bleichenbacher oracle.(CVE-2016-0704)

  - A NULL pointer dereference flaw was found in the way     OpenSSL performed a handshake when using the anonymous     Diffie-Hellman (DH) key exchange. A malicious server     could cause a DTLS client using OpenSSL to crash if     that client had anonymous DH cipher suites     enabled.(CVE-2014-3510)

  - While parsing an IPAddressFamily extension in an X.509     certificate, it is possible to do a one-byte overread.
    This would result in an incorrect text display of the     certificate. This bug has been present since 2006 and     is present in all versions of OpenSSL before 1.0.2m and     1.1.0g.(CVE-2017-3735)

  - The Network Security Services (NSS) library before     3.12.3, as used in Firefox GnuTLS before 2.6.4 and     2.7.4 OpenSSL 0.9.8 through 0.9.8k and other products     support MD2 with X.509 certificates, which might allow     remote attackers to spoof certificates by using MD2     design flaws to generate a hash collision in less than     brute-force time. NOTE: the scope of this issue is     currently limited because the amount of computation     required is still large.(CVE-2009-2409)

  - Constructed ASN.1 types with a recursive definition     (such as can be found in PKCS7) could eventually exceed     the stack given malicious input with excessive     recursion. This could result in a Denial Of Service     attack. There are no such structures used within     SSL/TLS that come from untrusted sources so this is     considered safe. Fixed in OpenSSL 1.1.0h (Affected     1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected     1.0.2b-1.0.2n).(CVE-2018-0739)

  - During key agreement in a TLS handshake using a DH(E)     based ciphersuite a malicious server can send a very     large prime value to the client. This will cause the     client to spend an unreasonably long period of time     generating a key for this prime resulting in a hang     until the client has finished. This could be exploited     in a Denial Of Service attack. Fixed in OpenSSL     1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL     1.0.2p-dev (Affected 1.0.2-1.0.2o).(CVE-2018-0732)

  - A NULL pointer dereference was found in the way OpenSSL     handled certain PKCS#7 inputs. An attacker able to make     an application using OpenSSL verify, decrypt, or parse     a specially crafted PKCS#7 input could cause that     application to crash. TLS/SSL clients and servers using     OpenSSL were not affected by this flaw.(CVE-2015-0289)

  - A flaw was discovered in the way OpenSSL handled DTLS     packets. A remote attacker could use this flaw to cause     a DTLS server or client using OpenSSL to crash or use     excessive amounts of memory.(CVE-2014-3506)

  - The kssl_keytab_is_available function in ssl/kssl.c in     OpenSSL before 0.9.8n, when Kerberos is enabled but     Kerberos configuration files cannot be opened, does not     check a certain return value, which allows remote     attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via SSL cipher     negotiation, as demonstrated by a chroot installation     of Dovecot or stunnel without Kerberos configuration     files inside the chroot.(CVE-2010-0433)

  - It was discovered that OpenSSL would accept ephemeral     RSA keys when using non-export RSA cipher suites. A     malicious server could make a TLS/SSL client using     OpenSSL use a weaker key exchange     method.(CVE-2015-0204)

  - It was found that OpenSSL's BigNumber Squaring     implementation could produce incorrect results under     certain special conditions. This flaw could possibly     affect certain OpenSSL library functionality, such as     RSA blinding. Note that this issue occurred rarely and     with a low probability, and there is currently no known     way of exploiting it.(CVE-2014-3570)

  - It was discovered that the OBJ_obj2txt() function could     fail to properly NUL-terminate its output. This could     possibly cause an application using OpenSSL functions     to format fields of X.509 certificates to disclose     portions of its memory.(CVE-2014-3508)

  - OpenSSL RSA key generation was found to be vulnerable     to cache side-channel attacks. An attacker with     sufficient access to mount cache timing attacks during     the RSA key generation process could recover parts of     the private key.(CVE-2018-0737)

The version of OpenSSL running on the remote host is affected by the following vulnerabilities :

  - In TLS connections, certain incorrectly formatted     records can cause an OpenSSL client or server to crash     due to a read attempt at NULL. OpenSSL before 0.9.8m     does not check for a NULL return value from bn_wexpand     function calls in (1) crypto/bn/bn_div.c, (2)     crypto/bn/bn_gf2m.c, (3) crypto/ec/ec2_smpl.c, and (4)     engines e_ubsec.c, which has an unspecified impact and     context-dependent attack vectors. (CVE-2009-3245)

  - The kssl_keytab_is_available function in ssl/kssl.c in     OpenSSL before 0.9.8n, when Kerberos is enabled but     Kerberos configuration files cannot be opened, does not     check a certain return value, which allows remote     attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via SSL cipher     negotiation, as demonstrated by a chroot installation of     Dovecot or stunnel without Kerberos configuration files     inside the chroot. (CVE-2010-0433)

  - The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL     0.9.8f through 0.9.8m allows remote attackers to cause a     denial of service (crash) via a malformed record in a     TLS connection that triggers a NULL pointer dereference,     related to the minor version number. (CVE-2010-0740)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

CVE-2009-3555 TLS: MITM attacks via session renegotiation

CVE-2010-0433 openssl: crash caused by a missing krb5_sname_to_principal() return value check

CVE-2009-3245 openssl: missing bn_wexpand return value checks

It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could cause an application using the OpenSSL library to crash or, possibly, execute arbitrary code.
(CVE-2009-3245)

A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746.
(CVE-2009-3555)

Refer to the following Knowledgebase article for additional details about the CVE-2009-3555 flaw:
http://kbase.redhat.com/faq/docs/DOC-20491

A missing return value check flaw was discovered in OpenSSL, that could possibly cause OpenSSL to call a Kerberos library function with invalid arguments, resulting in a NULL pointer dereference crash in the MIT Kerberos library. In certain configurations, a remote attacker could use this flaw to crash a TLS/SSL server using OpenSSL by requesting Kerberos cipher suites during the TLS handshake.
(CVE-2010-0433)

For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

The remote host is affected by the vulnerability described in GLSA-201110-01 (OpenSSL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in OpenSSL. Please review       the CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker could cause a Denial of Service, possibly       execute arbitrary code, bypass intended key requirements, force the       downgrade to unintended ciphers, bypass the need for knowledge of shared       secrets and successfully authenticate, bypass CRL validation, or obtain       sensitive information in applications that use OpenSSL.
  Workaround :

    There is no known workaround at this time.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0162 advisory.

  - openssl: missing bn_wexpand return value checks (CVE-2009-3245)

  - TLS: MITM attacks via session renegotiation (CVE-2009-3555)

  - openssl: crash caused by a missing krb5_sname_to_principal() return value check (CVE-2010-0433)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update fixes several security issues in openssl :

  - The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL     0.9.8f through 0.9.8m allows remote attackers to cause a     denial of service (crash) via a malformed record in a     TLS connection (CVE-2010-0740)

  - OpenSSL before 0.9.8m does not check for a NULL return     value from bn_wexpand function calls which has     unspecified impact and context-dependent attack vectors     (CVE-2009-3245)

  - The kssl_keytab_is_available function in ssl/kssl.c in     OpenSSL before 0.9.8n, when Kerberos is enabled but     Kerberos configuration files cannot be opened, could     allow remote attackers to cause a denial of service     (NULL pointer dereference and daemon crash)     (CVE-2010-0433)

  - Finally, this update provides support for secure     renegotiation, preventing men-in-the-middle attacks     (CVE-2009-3555).

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

Update :

Packages for 2009.0 are provided due to the Extended Maintenance Program.

New openssl packages are available for Slackware 11.0, 12.0, 12.1, 12.2, 13.0, and -current to fix security issues.

Updated openssl packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.

It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could cause an application using the OpenSSL library to crash or, possibly, execute arbitrary code.
(CVE-2009-3245)

A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746.
(CVE-2009-3555)

Refer to the following Knowledgebase article for additional details about the CVE-2009-3555 flaw:
http://kbase.redhat.com/faq/docs/DOC-20491

A missing return value check flaw was discovered in OpenSSL, that could possibly cause OpenSSL to call a Kerberos library function with invalid arguments, resulting in a NULL pointer dereference crash in the MIT Kerberos library. In certain configurations, a remote attacker could use this flaw to crash a TLS/SSL server using OpenSSL by requesting Kerberos cipher suites during the TLS handshake.
(CVE-2010-0433)

All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

According to its banner, the remote web server is running a version of OpenSSL older than 0.9.8n.  Such versions have the following vulnerabilities : 

  - Kerberos-enabled versions of OpenSSL do not check the return value when Kerberos configuration files cannot be opened, leading to a crash. (CVE-2010-0433)

  - Rejecting a SSL/TLS record with and incorrect version number can lead to a crash.  This only affects version 0.9.8m if a 'short' is 1 bits.  Otherwise it affects all versions back to and including 0.9.8f. (CVE-2010-0740)

The version of OpenSSL installed on the remote host is prior to 0.9.8n. It is, therefore, affected by multiple vulnerabilities as referenced in the 0.9.8n advisory.

  - The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL 0.9.8f through 0.9.8m allows remote attackers to     cause a denial of service (crash) via a malformed record in a TLS connection that triggers a NULL pointer     dereference, related to the minor version number. NOTE: some of these details are obtained from third     party information. (CVE-2010-0740)

  - The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but     Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote     attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher     negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration     files inside the chroot. (CVE-2010-0433)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
