Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated cups packages that fix three security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
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. (CVE-2010-0542)
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. (CVE-2010-0540)
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. (CVE-2010-1748)
