The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openssl: doapr_outch function does not verify that certain memory allocation succeeds (CVE-2016-2842)

  - OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent     modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a     disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a     different vulnerability than CVE-2010-4180. (CVE-2008-7270)

  - OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled,     does not properly prevent modification of the ciphersuite in the session cache, which allows remote     attackers to force the downgrade to an unintended cipher via vectors involving sniffing network traffic to     discover a session identifier. (CVE-2010-4180)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to its self-reported version number, the Symantec (formerly Blue Coat) Reporter installation running on the remote host is prior to 10.3.1.1. It is, therefore,  is affected by a denial of service vulnerability. The SSL/TLS implementation on the remote host allows clients to renegotiate connections. The computational requirements forrenegotiating a connection are asymmetrical between the client and the server, with the server performing several times more work. Since the remote host does not appear to limit the number of renegotiations for a single TLS / SSL connection, this permits a client to open several simultaneous connections and repeatedly renegotiate them, possibly leading to a denial of service condition.

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

According to its self-reported version number, the remote Juniper Junos device is affected by a denial of service vulnerability. The SSL/TLS implementation on the remote host allows clients to renegotiate connections. The computational requirements for renegotiating a connection are asymmetrical between the client and the server, with the server performing several times more work. Since the remote host does not appear to limit the number of renegotiations for a single TLS / SSL connection, this permits a client to open several simultaneous connections and repeatedly renegotiate them, possibly leading to a denial of service condition.

Note that this issue only affects devices with J-Web or the SSL service for JUNOScript enabled.

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openssl: Memory corruption in the ASN.1 encoder (CVE-2016-2108)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2006-7250, CVE-2012-1410. Reason: this     candidate was intended for one issue, but CVE users may have associated it with multiple unrelated issues.
    Notes: All CVE users should consult CVE-2006-7250 for the OpenSSL candidate or CVE-2012-1410 for the Kadu     candidate. All references and descriptions in this candidate have been removed to prevent accidental usage     (CVE-2006-7248)

  - 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 on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

This Apache2 LTSS roll-up update for SUSE Linux Enterprise 10 SP3 LTSS fixes the following security issues and bugs :

  - CVE-2012-4557: Denial of Service via special requests in     mod_proxy_ajp

  - CVE-2012-0883: improper LD_LIBRARY_PATH handling

  - CVE-2012-2687: filename escaping problem

  - CVE-2012-0031: Fixed a scoreboard corruption (shared mem     segment) by child causes crash of privileged parent     (invalid free()) during shutdown.

  - CVE-2012-0053: Fixed an issue in error responses that     could expose 'httpOnly' cookies when no custom     ErrorDocument is specified for status code 400'.

  - The SSL configuration template has been adjusted not to     suggested weak ciphers CVE-2007-6750: The     'mod_reqtimeout' module was backported from Apache     2.2.21 to help mitigate the 'Slowloris' Denial of     Service attack.

    You need to enable the 'mod_reqtimeout' module in your     existing apache configuration to make it effective, e.g.
    in the APACHE_MODULES line in /etc/sysconfig/apache2.

  - CVE-2011-3639, CVE-2011-3368, CVE-2011-4317: This update     also includes several fixes for a mod_proxy reverse     exposure via RewriteRule or ProxyPassMatch directives.

  - CVE-2011-1473: Fixed the SSL renegotiation DoS by     disabling renegotiation by default.

  - CVE-2011-3607: Integer overflow in ap_pregsub function     resulting in a heap-based buffer overflow could     potentially allow local attackers to gain privileges

Additionally, some non-security bugs have been fixed which are listed in the changelog file.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update fixes several security issues in the Apache2 webserver.
