6 August 2008

xine-lib vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 8.04 LTS
  • Ubuntu 7.10
  • Ubuntu 7.04
  • Ubuntu 6.06 LTS

Software Description

  • xine-lib

Details

Alin Rad Pop discovered an array index vulnerability in the SDP parser. If a user or automated system were tricked into opening a malicious RTSP stream, a remote attacker may be able to execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-0073)

Luigi Auriemma discovered that xine-lib did not properly check buffer sizes in the RTSP header-handling code. If xine-lib opened an RTSP stream with crafted SDP attributes, a remote attacker may be able to execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-0225, CVE-2008-0238)

Damian Frizza and Alfredo Ortega discovered that xine-lib did not properly validate FLAC tags. If a user or automated system were tricked into opening a crafted FLAC file, a remote attacker may be able to execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-0486)

It was discovered that the ASF demuxer in xine-lib did not properly check the length if the ASF header. If a user or automated system were tricked into opening a crafted ASF file, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-1110)

It was discovered that the Matroska demuxer in xine-lib did not properly verify frame sizes. If xine-lib opened a crafted ASF file, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-1161)

Luigi Auriemma discovered multiple integer overflows in xine-lib. If a user or automated system were tricked into opening a crafted FLV, MOV, RM, MVE, MKV or CAK file, a remote attacker may be able to execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-1482)

It was discovered that xine-lib did not properly validate its input when processing Speex file headers. If a user or automated system were tricked into opening a specially crafted Speex file, an attacker could create a denial of service or possibly execute arbitrary code as the user invoking the program. (CVE-2008-1686)

Guido Landi discovered a stack-based buffer overflow in xine-lib when processing NSF files. If xine-lib opened a specially crafted NSF file with a long NSF title, an attacker could create a denial of service or possibly execute arbitrary code as the user invoking the program. (CVE-2008-1878)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04 LTS
libxine1 - 1.1.11.1-1ubuntu3.1
Ubuntu 7.10
libxine1 - 1.1.7-1ubuntu1.3
Ubuntu 7.04
libxine-main1 - 1.1.4-2ubuntu3.1
Ubuntu 6.06 LTS
libxine-main1 - 1.1.1+ubuntu2-7.9

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

After a standard system upgrade you need to restart applications linked against xine-lib to effect the necessary changes.
