Debian-specific: no
CVE IDs : CAN-2005-1769 CAN-2005-2095

Several vulnerabilities have been discovered in Squirrelmail, a commonly used webmail system. The Common Vulnerabilities and Exposures project identifies the following problems:

CAN-2005-1769

Martijn Brinkers discovered cross-site scripting vulnerabilities that allow remote attackers to inject arbitrary web script or HTML in the URL and e-mail messages.

CAN-2005-2095

James Bercegay of GulfTech Security discovered a vulnerability in the variable handling which could lead to attackers altering other people's preferences and possibly reading them, writing files at any location writable for www-data and cross site scripting.

For the old stable distribution (woody) these problems have been fixed in version 1.2.6-4.

For the stable distribution (sarge) these problems have been fixed in version 1.4.4-6sarge1.

For the unstable distribution (sid) these problems have been fixed in version 1.4.4-6sarge1.

We recommend that you upgrade your squirrelmail package.
