xli - buffer overflow, input sanitising, integer overflow

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.

• 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.
