PLATFORM: Debian GNU/Linux 4.0 (etch) DAMAGE: Execution of arbitrary code. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. A remote user who can coerce a user to open ASSESSMENT: a specially crafted document in one of the xine-lib formats could run arbitrary code as the logged-in user. ______________________________________________________________________________ CVSS 2 BASE SCORE: 5.8 TEMPORAL SCORE: 4.5 VECTOR: (AV:N/AC:M/Au:N/C:P/I:P/A:N/E:POC/RL:OF/RC:C) ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/s-302.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2008/dsa-1586 CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2008-1482 CVE-2008-1686 CVE-2008-1878 ______________________________________________________________________________ [***** Start Debian Security Advisory DSA-1586-1 *****] Debian Security Advisory DSA-1586-1 xine-lib -- multiple vulnerabilities Date Reported: 22 May 2008 Affected Packages: xine-lib Vulnerable: Yes Security database references: In Mitre's CVE dictionary: CVE-2008-1482, CVE-2008-1686, CVE-2008-1878. More information: Multiple vulnerabilities have been discovered in xine-lib, a library which supplies most of the application functionality of the xine multimedia player. The Common Vulnerabilities and Exposures project identifies the following three problems: CVE-2008-1482 Integer overflow vulnerabilities exist in xine's FLV, QuickTime, RealMedia, MVE and CAK demuxers, as well as the EBML parser used by the Matroska demuxer. These weaknesses allow an attacker to overflow heap buffers and potentially execute arbitrary code by supplying a maliciously crafted file of those types. CVE-2008-1686 Insufficient input validation in the Speex implementation used by this version of xine enables an invalid array access and the execution of arbitrary code by supplying a maliciously crafted Speex file. CVE-2008-1878 Inadequate bounds checking in the NES Sound Format (NSF) demuxer enables a stack buffer overflow and the execution of arbitrary code through a maliciously crafted NSF file. For the stable distribution (etch), these problems have been fixed in version 1.1.2+dfsg-7. For the unstable distribution (sid), these problems have been fixed in version 1.1.12-2. We recommend that you upgrade your xine-lib packages.
