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:


    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.


    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.


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

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.
