xine-lib 1.1.12, and other 1.1.15 and earlier versions, relies on an untrusted input value to determine the memory allocation and does not check the result for (1) the MATROSKA_ID_TR_CODECPRIVATE track entry element processed by demux_matroska.c; and (2) PROP_TAG, (3) MDPR_TAG, and (4) CONT_TAG chunks processed by the real_parse_headers function in demux_real.c; which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) or possibly execute arbitrary code via a crafted value.

This update of xine fixes multiple buffer overflows while parsing files :

    (CVE-2008-5248)

The remote host is affected by the vulnerability described in GLSA-201006-04 (xine-lib: User-assisted execution of arbitrary code)

    Multiple vulnerabilities have been reported in xine-lib. Please review     the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to play a specially crafted video     file or stream with a player using xine-lib, potentially resulting in     the execution of arbitrary code with the privileges of the user running     the application.
  Workaround :

    There is no known workaround at this time.

Vulnerabilities have been discovered and corrected in xine-lib :

Failure on Ogg files manipulation can lead remote attackers to cause a denial of service by using crafted files (CVE-2008-3231).

Failure on manipulation of either MNG or Real or MOD files can lead remote attackers to cause a denial of service by using crafted files (CVE: CVE-2008-5233).

Heap-based overflow allows remote attackers to execute arbitrary code by using Quicktime media files holding crafted metadata (CVE-2008-5234).

Heap-based overflow allows remote attackers to execute arbitrary code by using either crafted Matroska or Real media files (CVE-2008-5236).

Failure on manipulation of either MNG or Quicktime files can lead remote attackers to cause a denial of service by using crafted files (CVE-2008-5237).

Multiple heap-based overflow on input plugins (http, net, smb, dvd, dvb, rtsp, rtp, pvr, pnm, file, gnome_vfs, mms) allow attackers to execute arbitrary code by handling that input channels. Further this problem can even lead attackers to cause denial of service (CVE-2008-5239).

Heap-based overflow allows attackers to execute arbitrary code by using crafted Matroska media files (MATROSKA_ID_TR_CODECPRIVATE track entry element). Further a failure on handling of Real media files (CONT_TAG header) can lead to a denial of service attack (CVE-2008-5240).

Integer underflow allows remote attackers to cause denial of service by using Quicktime media files (CVE-2008-5241).

Failure on manipulation of Real media files can lead remote attackers to cause a denial of service by indexing an allocated buffer with a certain input value in a crafted file (CVE-2008-5243).

Vulnerabilities of unknown impact - possibly buffer overflow - caused by a condition of video frame preallocation before ascertaining the required length in V4L video input plugin (CVE-2008-5245).

Heap-based overflow allows remote attackers to execute arbitrary code by using crafted media files. This vulnerability is in the manipulation of ID3 audio file data tagging mainly used in MP3 file formats (CVE-2008-5246).

Integer overflow in the qt_error parse_trak_atom function in demuxers/demux_qt.c in xine-lib 1.1.16.2 and earlier allows remote attackers to execute arbitrary code via a Quicktime movie file with a large count value in an STTS atom, which triggers a heap-based buffer overflow (CVE-2009-1274)

Integer overflow in the 4xm demuxer (demuxers/demux_4xm.c) in xine-lib 1.1.16.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a 4X movie file with a large current_track value, a similar issue to CVE-2009-0385 (CVE-2009-0698)

Multiple vulnerabilities were fixed in libxine 1.1.16.2.

Tobias Klein reports :

FFmpeg contains a type conversion vulnerability while parsing malformed 4X movie files. The vulnerability may be exploited by a (remote) attacker to execute arbitrary code in the context of FFmpeg or an application using the FFmpeg library.

Note: A similar issue also affects xine-lib < version 1.1.16.2.

xine developers report :

This update provides the fix for all these security issues found in xine-lib 1.1.11 of Mandriva 2008.1. The vulnerabilities:
CVE-2008-5234, CVE-2008-5236, CVE-2008-5237, CVE-2008-5239, CVE-2008-5240, CVE-2008-5243 are found in xine-lib 1.1.15 of Mandriva 2009.0 and are also fixed by this update.

This updates xine-lib to the upstream 1.1.16 release. This fixes several bugs, including the security issues CVE-2008-5234 vector 1, CVE-2008-5236, CVE-2008-5237, CVE-2008-5239, CVE-2008-5240 vectors 3 & 4 and CVE-2008-5243. See http://sourceforge.net/project/shownotes.php?release_id=652075&group_i d=9655 for the full list of changes. In addition, the Fedora xine-lib package now includes the demuxers for the MPEG container format, which are not patent- encumbered. (The decoders for actual MPEG video and audio data are still excluded due to software patents.)

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

This release fixes multiple bugs and security issues: - DoS via corrupted Ogg files (CVE-2008-3231) - multiple possible buffer overflows detailed in oCERT-2008-008 For more details, see:
http://sourceforge.net/project/shownotes.php?release_id=619869&group_i d=9655 http://www.ocert.org/advisories/ocert-2008-008.html NOTE: A coordinated release with 3rd-party repos was not possible, so this update may result in dependency issues with currently-installed xine-lib-extras-* rpms. This temporary problem will be rectified asap.
