Description

Updated cups packages that fix denial of service issues, a security information leak, as well as other various bugs are now available.

The Common UNIX Printing System (CUPS) is a print spooler. During a source code audit, Chris Evans discovered a number of integer overflow bugs that affect xpdf. CUPS contains a copy of the xpdf code used for parsing PDF files and is therefore affected by these bugs. An attacker who has the ability to send a malicious PDF file to a printer could cause CUPS to crash or possibly execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0888 to this issue. When set up to print to a shared printer via Samba, CUPS would authenticate with that shared printer using a username and password. By default, the username and password used to connect to the Samba share is written into the error log file. A local user who is able to read the error log file could collect these usernames and passwords. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0923 to this issue. These updated packages also include a fix that prevents some CUPS configuration files from being accidentally replaced. All users of CUPS should upgrade to these updated packages, which resolve these issues.
