Alexander Cherepanov discovered that bsdcpio, an implementation of the
cpio program part of the libarchive project, is susceptible to a
directory traversal vulnerability via absolute paths.

Multiple security issues have been found in Icedove, Debian’s version of
the Mozilla Thunderbird mail and news client: Multiple memory safety
errors and implementation errors may lead to the execution of arbitrary
code or information disclosure.

Jakub Wilk discovered that unace, an utility to extract, test and view
.ace archives, contained an integer overflow leading to a buffer
overflow. If a user or automated system were tricked into processing a
specially crafted ace archive, an attacker could cause a denial of
service (application crash) or, possibly, execute arbitrary code.

Multiple vulnerabilities have been discovered in Request Tracker, an
extensible trouble-ticket tracking system. The Common Vulnerabilities
and Exposures project identifies the following problems:

Multiple security issues have been found in Iceweasel, Debian’s version
of the Mozilla Firefox web browser: Multiple memory safety errors and
implementation errors may lead to the execution of arbitrary code or
information disclosure.

It was discovered that libgtk2-perl, a Perl interface to the 2.x series
of the Gimp Toolkit library, incorrectly frees memory which GTK+ still
holds onto and might access later, leading to denial of service
(application crash) or, potentially, to arbitrary code execution.

Peter De Wachter discovered that CUPS, the Common UNIX Printing
System, did not correctly parse compressed raster files. By submitting
a specially crafted raster file, a remote attacker could use this
vulnerability to trigger a buffer overflow.

Mateusz Kocielski and Marek Kroemeke discovered that an integer overflow
in IGMP processing may result in denial of service through malformed
IGMP packets.

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service, information leaks or privilege
escalation.

Richard van Eeden of Microsoft Vulnerability Research discovered that
Samba, a SMB/CIFS file, print, and login server for Unix, contains a
flaw in the netlogon server code which allows remote code execution with
root privileges from an unauthenticated connection.
