MDVSA-2012:076: ffmpeg

Multiple vulnerabilities has been found and corrected in ffmpeg:

The Matroska format decoder in FFmpeg does not properly allocate
memory, which allows remote attackers to execute arbitrary code via
a crafted file (CVE-2011-3362, CVE-2011-3504).

cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause
a denial of service (incorrect write operation and application
crash) via an invalid bitstream in a Chinese AVS video (aka CAVS)
file, related to the decode_residual_block, check_for_slice,
and cavs_decode_frame functions, a different vulnerability than
CVE-2011-3362 (CVE-2011-3973).

Integer signedness error in the decode_residual_inter function in
cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause a
denial of service (incorrect write operation and application crash)
via an invalid bitstream in a Chinese AVS video (aka CAVS) file,
a different vulnerability than CVE-2011-3362 (CVE-2011-3974).

Double free vulnerability in the Theora decoder in FFmpeg allows remote
attackers to cause a denial of service or possibly have unspecified
other impact via a crafted stream (CVE-2011-3892).

FFmpeg does not properly implement the MKV and Vorbis media
handlers, which allows remote attackers to cause a denial of service
(out-of-bounds read) via unspecified vectors (CVE-2011-3893).

Heap-based buffer overflow in the Vorbis decoder in FFmpeg allows
remote attackers to cause a denial of service or possibly have
unspecified other impact via a crafted stream (CVE-2011-3895).

An error within the QDM2 decoder (libavcodec/qdm2.c) can be exploited
to cause a buffer overflow (CVE-2011-4351).

An integer overflow error within the "vp3_dequant()" function
(libavcodec/vp3.c) can be exploited to cause a buffer overflow
(CVE-2011-4352).

Errors within the "av_image_fill_pointers()", the "vp5_parse_coeff()",
and the "vp6_parse_coeff()" functions can be exploited to trigger
out-of-bounds reads (CVE-2011-4353).

It was discovered that Libav incorrectly handled certain malformed
VMD files. If a user were tricked into opening a crafted VMD file,
an attacker could cause a denial of service via application crash,
or possibly execute arbitrary code with the privileges of the user
invoking the program (CVE-2011-4364).

It was discovered that Libav incorrectly handled certain malformed SVQ1
streams. If a user were tricked into opening a crafted SVQ1 stream
file, an attacker could cause a denial of service via application
crash, or possibly execute arbitrary code with the privileges of the
user invoking the program (CVE-2011-4579).

Multiple input validations in the decoders/ demuxers for Westwood
Studios VQA, Apple MJPEG-B, Theora, Matroska, Vorbis, Sony ATRAC3,
DV, NSV, files could lead to the execution of arbitrary code
(CVE-2011-3929, CVE-2011-3936, CVE-2011-3937, CVE-2011-3940,
CVE-2011-3945, CVE-2011-3947, CVE-2012-0853, CVE-2012-0858).

The updated packages have been upgraded to the 0.7.12 version where
these issues has been corrected.

Additionally a couple of packages needed to be rebuilt for the new
ffmpeg version and is also being provided with this advisory.

MDVA-2012:041: mysql

This is a maintenance and bugfix release that upgrades mysql to the
latest version which resolves various upstream bugs.

MDVSA-2012:073: openssl

A vulnerability has been found and corrected in openssl:

A flaw in the OpenSSL handling of CBC mode ciphersuites in DTLS can
be exploited in a denial of service attack on both clients and servers
(CVE-2012-2333).

The updated packages have been patched to correct this issue.

MDVSA-2012:072: roundcubemail

Multiple vulnerabilities has been found and corrected in roundcubemail:

The login form in Roundcube Webmail before 0.5.1 does not properly
handle a correctly authenticated but unintended login attempt, which
makes it easier for remote authenticated users to obtain sensitive
information by arranging for a victim to login to the attacker's
account and then compose an e-mail message, related to a login CSRF
issue (CVE-2011-1491).

steps/utils/modcss.inc in Roundcube Webmail before 0.5.1 does
not properly verify that a request is an expected request for an
external Cascading Style Sheets (CSS) stylesheet, which allows remote
authenticated users to trigger arbitrary outbound TCP connections
from the server, and possibly obtain sensitive information, via a
crafted request (CVE-2011-1492).

Cross-site scripting (XSS) vulnerability in the UI messages
functionality in Roundcube Webmail before 0.5.4 allows remote attackers
to inject arbitrary web script or HTML via the _mbox parameter to
the default URI (CVE-2011-2937).

include/iniset.php in Roundcube Webmail 0.5.4 and earlier, when PHP
5.3.7 or 5.3.8 is used, allows remote attackers to trigger a GET
request for an arbitrary URL, and cause a denial of service (resource
consumption and inbox outage), via a Subject header containing only
a URL, a related issue to CVE-2011-3379 (CVE-2011-4078).

The updated packages have been upgraded to the 0.7.2 version which
is not affected by these issues.

MDVSA-2012:071: php

This is a bugfix and security advisory that upgrades php to the
latest 5.3.13 version for Mandriva Linux Enterprise 5.2 which resolves
numerous upstream bugs in php. Please refer to the following Mandriva
advisories for further information:
MDVA-2012:004, MDVSA-2011:165, MDVSA-2011:166, MDVSA-2011:180,
MDVSA-2011:197, MDVSA-2012:065, MDVSA-2012:068, MDVSA-2012:068-1.

MDVSA-2012:068-1: php

A vulnerability has been found and corrected in php(-cgi):

PHP-CGI-based setups contain a vulnerability when parsing query string
parameters from php files. A remote unauthenticated attacker could
obtain sensitive information, cause a denial of service condition or
may be able to execute arbitrary code with the privileges of the web
server (CVE-2012-1823).

The updated packages have been patched to correct this issue.

Update:

It was discovered that the previous fix for the CVE-2012-1823
vulnerability was incomplete (CVE-2012-2335, CVE-2012-2336). The
updated packages provides the latest version (5.3.13) which provides
a solution to this flaw.

MDVSA-2012:070: samba

A vulnerability has been found and corrected in samba:

A file existence dislosure flaw was found in the way mount.cifs tool
of the Samba SMB/CIFS tools suite performed mount of a Linux CIFS
(Common Internet File System) filesystem. A local user, able to
mount a remote CIFS share / target to a local directory could use
this flaw to confirm (non) existence of a file system object (file,
directory or process descriptor) via error messages generated during
the mount.cifs tool run (CVE-2012-1586).

The updated packages have been patched to correct this issue.
