From the Ubuntu advisory:

Gary Kwong, Jesse Ruderman, Christian Holler, Bob Clary, Kyle Huey, Ed Morley, Chris Lord, Boris Zbarsky, Julian Seward, Bill McCloskey, and Andrew McCreight discovered multiple memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-5842, CVE-2012-5843)

Jonathan Stephens discovered that combining vectors involving the setting of Cascading Style Sheets (CSS) properties in conjunction with SVG text could cause Firefox to crash. If a user were tricked into opening a malicious web page, an attacker could cause a denial of service via application crash or execute arbitrary code with the privliges of the user invoking the program. (CVE-2012-5836)

It was discovered that if a javascript: URL is selected from the list of Firefox "new tab" page, the script will inherit the privileges of the privileged "new tab" page. This allows for the execution of locally installed programs if a user can be convinced to save a bookmark of a malicious javascript: URL. (CVE-2012-4203)

Scott Bell discovered a memory corruption issue in the JavaScript engine. If a user were tricked into opening a malicious website, an attacker could exploit this to execute arbitrary JavaScript code within the context of another website or arbitrary code as the user invoking the program. (CVE-2012-4204)

Gabor Krizsanits discovered that XMLHttpRequest objects created within sandboxes have the system principal instead of the sandbox principal. This can lead to cross-site request forgery (CSRF) or information theft via an add-on running untrusted code in a sandbox. (CVE-2012-4205)

Peter Van der Beken discovered XrayWrapper implementation in Firefox does not consider the compartment during property filtering. An attacker could use this to bypass intended chrome-only restrictions on reading DOM object properties via a crafted web site. (CVE-2012-4208)

Abhishek Arya discovered multiple use-after-free and buffer overflow issues in Firefox. If a user were tricked into opening a malicious page, an attacker could exploit these to execute arbitrary code as the user invoking the program. (CVE-2012-4214, CVE-2012-4215, CVE-2012-4216, CVE-2012-5829, CVE-2012-5839, CVE-2012-5840, CVE-2012-4212, CVE-2012-4213, CVE-2012-4217, CVE-2012-4218)

Several memory corruption flaws were discovered in Firefox. If a user were tricked into opening a malicious page, an attacker could exploit these to execute arbitrary code as the user invoking the program. (CVE-2012-5830, CVE-2012-5833, CVE-2012-5835, CVE-2012-5838)

From the openSUSE advisory:

The source code without this patch caused hv_kvp_daemon to exit when it processed a spoofed Netlink packet which has been sent from an untrusted local user. Now Netlink messages with a non-zero nl_pid source address are ignored and a warning is printed into the syslog. This fixes the previous change from CVE-2012-2669.

Multiple integer overflows in the (1) _objalloc_alloc function in objalloc.c and (2) objalloc_alloc macro in include/objalloc.h in GNU libiberty, as used by binutils 2.22, allow remote attackers to cause a denial of service (crash) via vectors related to the "addition of CHUNK_HEADER_SIZE to the length," which triggers a heap-based buffer overflow.

From the Red Hat Bugzilla entry:

A flaw has been found in the way Linux kernel's KVM subsystem handled vcpu->arch.cr4 X86_CR4_OSXSAVE bit set upon guest enter. On hosts without the XSAVE feature an unprivileged local user could use this flaw to crash the system.

From the Fedora advisory:

The libsocialweb library is prone to a security vulnerability that allows attackers to perform man-in-the-middle attacks.

Remote attackers can exploit this issue to gain access to sensitive information or modify the integrity of user accounts. Other attacks are also possible.

Xi Wang and Florian Weimer discovered that libssh incorrectly handled memory. A remote attacker could use this to cause libssh to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2012-4559, CVE-2012-4560, CVE-2012-4561, CVE-2012-4562)

From the SUSE advisory:

This update of libssh fixes multiple integer overflows. CVE-2012-4562 has been assigned to this issue.

Version 3.2.1 fixes the handling of embedded null characters in input strings entered through the Python interface. The bug could be used to cause denial of service conditions and possibly other problems. Users of these interfaces are recommended to upgrade to this release. Applications that use the native C++ library directly (this includes all well known desktop applications) are not affected by this bug and no changes to the native library have been made in this release.

From the Novell advisory:

Specially-crafted HTTP header can cause a Denial of Service (infinite loop) in lighttpd.

MantisBT before 1.2.12 does not use an expected default value during decisions about whether a user may modify the status of a bug, which allows remote authenticated users to bypass intended access restrictions and make status changes by leveraging a blank value for a per-status setting. (CVE-2012-5522)

core/email_api.php in MantisBT before 1.2.12 does not properly manage the sending of e-mail notifications about restricted bugs, which might allow remote authenticated users to obtain sensitive information by adding a note to a bug before losing permission to view that bug. (CVE-2012-5523)

The Dropbox Repository File Picker in Moodle 2.1.x before 2.1.9, 2.2.x before 2.2.6, and 2.3.x before 2.3.3 allows remote authenticated users to access the Dropbox of a different user by leveraging an unattended workstation after a logout.

From the Fedora advisory:

A security flaw was found in the way Performance Co-Pilot (PCP), a framework and services to support system-level performance monitoring and performance management, performed management of its temporary files used by various services from the suite. A local attacker could use this flaw to conduct symbolic link attacks (alter or remove different system files, accessible with the privileges of the user running the PCP suite, than it was originally intended).

CGI.pm module before 3.63 for Perl does not properly escape newlines in (1) Set-Cookie or (2) P3P headers, which might allow remote attackers to inject arbitrary headers into responses from applications that use CGI.pm.

James Clawson discovered that rssh, a restricted shell for OpenSSH to be used with scp/sftp, rdist and cvs, was not correctly filtering command line options. This could be used to force the execution of a remote script and thus allow arbitrary command execution.

From the Ubuntu advisory:

It was discovered that the Apache Tomcat HTTP NIO connector incorrectly handled header data. A remote attacker could cause a denial of service by sending requests with a large amount of header data. (CVE-2012-2733)

It was discovered that Apache Tomcat incorrectly handled DIGEST authentication. A remote attacker could possibly use these flaws to perform a replay attack and bypass authentication. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887)

From the Ubuntu advisory:

It was discovered that unity-firefox-extension incorrectly handled certain callbacks. A remote attacker could use this issue to cause unity-firefox-extension to crash, resulting in a denial of service, or possibly execute arbitrary code.

From the Mageia advisory:

libpng_plugin in VideoLAN VLC media player 2.0.3 allows remote attackers to cause a denial of service (application crash) via a crafted PNG file (CVE-2012-5470).

added weechat-fix-hook_process-shell-injection.patch which fixes a shell injection vulnerability in the hook_process function (bnc#790217, CVE-2012-5534)
