cups security update (RHSA-2010-0490)

Original Release Date: July 6, 2010
Last Revised: March 1, 2012
Number: ASA-2010-173
Risk Level: Low
Advisory Version: 5.0
Advisory Status: Interim

1. Overview:

The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. The CUPS "texttops" filter converts text files to PostScript.

A missing memory allocation failure check flaw, leading to a NULL pointer dereference, was found in the CUPS "texttops" filter. An attacker could create a malicious text file that would cause "texttops" to crash or, potentially, execute arbitrary code as the "lp" user if the file was printed. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0542 to this issue.

A Cross-Site Request Forgery (CSRF) issue was found in the CUPS web interface. If a remote attacker could trick a user, who is logged into the CUPS web interface as an administrator, into visiting a specially-crafted website, the attacker could reconfigure and disable CUPS, and gain access to print jobs and system files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0540 to this issue.

Note: As a result of the fix for CVE-2010-0540, cookies must now be enabled in your web browser to use the CUPS web interface.

An uninitialized memory read issue was found in the CUPS web interface. If an attacker had access to the CUPS web interface, they could use a specially-crafted URL to leverage this flaw to read a limited amount of memory from the cupsd process, possibly obtaining sensitive information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1748 to this issue.

Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems.
