Package : xli
Vulnerability : buffer overflow, input sanitising, integer overflow
Problem-Type : local (remote)
Debian-specific: no
CVE IDs : CAN-2001-0775 CAN-2005-0638 CAN-2005-0639
BugTraq ID : 3006
Debian Bug : 298039

Several vulnerabilities have been discovered in xli, an image viewer for X11. The Common Vulnerabilities and Exposures project identifies the following problems:

CAN-2001-0775

A buffer overflow in the decoder for FACES format images could be exploited by an attacker to execute arbitrary code. This problem has been fixed in xloadimage in DSA 069 already.

CAN-2005-0638

Tavis Ormandy of the Gentoo Linux Security Audit Team has reported a flaw in the handling of compressed images, where shell meta-characters are not adequately escaped.

CAN-2005-0639

Insufficient validation of image properties in have been discovered which could potentially result in buffer management errors.

For the stable distribution (woody) these problems have been fixed in version 1.17.0-11woody1.

For the unstable distribution (sid) these problems have been fixed in version 1.17.0-18.

We recommend that you upgrade your xli package.
