S-302: xine-lib Vulnerabilities

[Debian Security Advisory DSA-1586-1]

May 30, 2008 13:00 GMT


PROBLEM:	Multiple vulnerabilities have been discovered in xine-lib, a library which supplies most of the application functionality of the xine multimedia player.
PLATFORM:	Debian GNU/Linux 4.0 (etch)
DAMAGE:	Execution of arbitrary code.
SOLUTION:	Upgrade to the appropriate version.

VULNERABILITY ASSESSMENT:	The risk is MEDIUM. A remote user who can coerce a user to open a specially crafted document in one of the xine-lib formats could run arbitrary code as the logged-in user.

CVSS 2 BASE SCORE: TEMPORAL SCORE: VECTOR:	5.8 4.5 (AV:N/AC:M/Au:N/C:P/I:P/A:N/E:POC/RL:OF/RC:C)

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.

Fixed in:

Debian GNU/Linux 4.0 (etch)
