Debian Security Advisory
DSA-191-1 squirrelmail -- cross site scripting
- Date Reported:
- 07 Nov 2002
- Affected Packages:
- Security database references:
- In the Bugtraq database (at SecurityFocus): BugTraq ID 5949, BugTraq ID 5763.
In Mitre's CVE dictionary: CVE-2002-1131, CVE-2002-1132, CVE-2002-1276.
- More information:
Several cross site scripting vulnerabilities have been found in squirrelmail, a feature-rich webmail package written in PHP4. The Common Vulnerabilities and Exposures (CVE) project identified the following vulnerabilities:
- CAN-2002-1131: User input is not always sanitized so execution of arbitrary code on a client computer is possible. This can happen after following a malicious URL or by viewing a malicious addressbook entry.
- CAN-2002-1132: Another problem could make it possible for an attacker to gain sensitive information under some conditions. When a malformed argument is appended to a link, an error page will be generated which contains the absolute pathname of the script. However, this information is available through the Contents file of the distribution anyway.
These problems have been fixed in version 1.2.6-1.1 for the current stable distribution (woody) and in version 1.2.8-1.1 for the unstable distribution (sid). The old stable distribution (potato) is not affected since it doesn't contain a squirrelmail package.
We recommend that you upgrade your squirrelmail package.
- Fixed in:
Debian GNU/Linux 3.0 (woody)
