Cisco Unified Communications Manager contains a memory leak vulnerability that could be triggered through the processing of malformed Session Initiation Protocol (SIP) messages. Exploitation of this vulnerability could cause an interruption of voice services. Cisco has released free software updates for supported Cisco Unified Communications Manager versions to address the vulnerability. A workaround exists for this SIP vulnerability.

Jabber Extensible Communications Platform and Cisco Unified Presence XML Denial of Service Vulnerability
A denial of service (DoS) vulnerability exists in Jabber Extensible Communications Platform (Jabber XCP) and Cisco Unified Presence. An unauthenticated, remote attacker could exploit this vulnerability by sending malicious XML to an affected server. Successful exploitation of this vulnerability could cause elevated memory and CPU utilization, resulting in memory exhaustion and process crashes. Repeated exploitation could result in a sustained DoS condition.
CVE-2011-2766
The FCGI (aka Fast CGI) module 0.70 through 0.73 for Perl, as used by CGI::Fast, uses environment variable values from one request during processing of a later request, which allows remote attackers to bypass authentication via crafted HTTP headers. (CVSS:7.5) (Last Update:2012-11-05)
CVE-2011-3348
The mod_proxy_ajp module in the Apache HTTP Server before 2.2.21, when used with mod_proxy_balancer in certain configurations, allows remote attackers to cause a denial of service (temporary “error state” in the backend server) via a malformed HTTP request. (CVSS:4.3) (Last Update:2013-11-15)

Apache HTTP Server 2.2.21 Released
The Apache Software Foundation and the Apache HTTP Server Project are
pleased to announce the release of version 2.2.21 of the Apache HTTP
Server ("Apache"). This version of Apache is principally a security
and bug fix release:
* SECURITY: CVE-2011-3348 (cve.mitre.org)
mod_proxy_ajp when combined with mod_proxy_balancer: Prevents
unrecognized HTTP methods from marking ajp: balancer members
in an error state, avoiding denial of service.
* SECURITY: CVE-2011-3192 (cve.mitre.org)
core: Further fixes to the handling of byte-range requests to use
less memory, to avoid denial of service. This patch includes fixes
to the patch introduced in release 2.2.20 for protocol compliance,
as well as the MaxRanges directive.
Note the further advisories on the state of CVE-2011-3192 will no longer
be broadcast, but will be kept up to date at;
http://httpd.apache.org/security/CVE-2011-3192.txt
We consider this release to be the best version of Apache available, and
encourage users of all prior versions to upgrade.
Apache HTTP Server 2.2.21 is available for download from:
http://httpd.apache.org/download.cgi
Please see the CHANGES_2.2 file, linked from the download page, for a
full list of changes. A condensed list, CHANGES_2.2.21 provides the
complete list of changes since 2.2.19. A summary of all of the security
vulnerabilities addressed in this and earlier releases is available:
http://httpd.apache.org/security/vulnerabilities_22.html
This release includes the Apache Portable Runtime (APR) version 1.4.5
and APR Utility Library (APR-util) version 1.3.12, bundled with the tar
and zip distributions. The APR libraries libapr and libaprutil (and
on Win32, libapriconv version 1.2.1) must all be updated to ensure
binary compatibility and address many known security and platform bugs.
Apache 2.2 offers numerous enhancements, improvements, and performance
boosts over the 2.0 codebase. For an overview of new features
introduced since 2.0 please see:
http://httpd.apache.org/docs/2.2/new_features_2_2.html
This release builds on and extends the Apache 2.0 API. Modules written
for Apache 2.0 will need to be recompiled in order to run with Apache
2.2, and require minimal or no source code changes.
http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/VERSIONING
When upgrading or installing this version of Apache, please bear in mind
that if you intend to use Apache with one of the threaded MPMs (other
than the Prefork MPM), you must ensure that any modules you will be
using (and the libraries they depend on) are thread-safe.
