The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2009-1335 advisory.

  - 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 mime_hdr_cmp function in crypto/asn1/asn_mime.c in OpenSSL 0.9.8t and earlier allows remote attackers     to cause a denial of service (NULL pointer dereference and application crash) via a crafted S/MIME     message. (CVE-2006-7250)

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

Updated openssl packages that fix several security issues, various bugs, and add enhancements are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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. Datagram TLS (DTLS) is a protocol based on TLS that is capable of securing datagram transport (for example, UDP).

Multiple denial of service flaws were discovered in OpenSSL's DTLS implementation. A remote attacker could use these flaws to cause a DTLS server to use excessive amounts of memory, or crash on an invalid memory access or NULL pointer dereference. (CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386, CVE-2009-1387)

Note: These flaws only affect applications that use DTLS. Red Hat does not ship any DTLS client or server applications in Red Hat Enterprise Linux.

An input validation flaw was found in the handling of the BMPString and UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex() function. An attacker could use this flaw to create a specially crafted X.509 certificate that could cause applications using the affected function to crash when printing certificate contents. (CVE-2009-0590)

Note: The affected function is rarely used. No application shipped with Red Hat Enterprise Linux calls this function, for example.

These updated packages also fix the following bugs :

* 'openssl smime -verify -in' verifies the signature of the input file and the '-verify' switch expects a signed or encrypted input file.
Previously, running openssl on an S/MIME file that was not encrypted or signed caused openssl to segfault. With this update, the input file is now checked for a signature or encryption. Consequently, openssl now returns an error and quits when attempting to verify an unencrypted or unsigned S/MIME file. (BZ#472440)

* when generating RSA keys, pairwise tests were called even in non-FIPS mode. This prevented small keys from being generated. With this update, generating keys in non-FIPS mode no longer calls the pairwise tests and keys as small as 32-bits can be generated in this mode. Note: In FIPS mode, pairwise tests are still called and keys generated in this mode must still be 1024-bits or larger. (BZ#479817)

As well, these updated packages add the following enhancements :

* both the libcrypto and libssl shared libraries, which are part of the OpenSSL FIPS module, are now checked for integrity on initialization of FIPS mode. (BZ#475798)

* an issuing Certificate Authority (CA) allows multiple certificate templates to inherit the CA's Common Name (CN). Because this CN is used as a unique identifier, each template had to have its own Certificate Revocation List (CRL). With this update, multiple CRLs with the same subject name can now be stored in a X509_STORE structure, with their signature field being used to distinguish between them. (BZ#457134)

* the fipscheck library is no longer needed for rebuilding the openssl source RPM. (BZ#475798)

OpenSSL users should upgrade to these updated packages, which resolve these issues and add these enhancements.

The following security issues have been fixed :

  - Specially crafted MIME headers could cause openssl's     ans1 parser to dereference a NULL pointer leading to a     Denial of Service (CVE-2006-7250) or fail verfication.
    (CVE-2012-1165)

  - The implementation of Cryptographic Message Syntax (CMS)     and PKCS #7 in OpenSSL was vulnerable to a Million     Message Attack (MMA) adaptive chosen ciphertext attack.
    (CVE-2012-0884)

Additionally, the following issues have been fixed :

  - Free headers after use in error message. (bnc#749213)

  - Symmetric crypto errors in PKCS7_decrypt. (bnc#749210)

  - Memory leak when creating public keys. (bnc#749735)

It was discovered that OpenSSL could be made to dereference a NULL pointer when processing S/MIME messages. A remote attacker could use this to cause a denial of service. These issues did not affect Ubuntu 8.04 LTS. (CVE-2006-7250, CVE-2012-1165)

Tavis Ormandy discovered that OpenSSL did not properly perform bounds checking when processing DER data via BIO or FILE functions. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. (CVE-2012-2110).
