-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 191-1 security@debian.org http://www.debian.org/security/ Martin Schulze November 7th, 2002 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : squirrelmail Vulnerability : cross site scripting Problem-Type : remote Debian-specific: no BugTraq ID : 5949 CVE ID : CAN-2002-1131 CAN-2002-1132 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: 1. 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. 2. 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 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. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
