Description

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 already been fixed in xloadimage in DSA 069.

 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.
