Important: cups security update
Security Advisory: Important
Updated cups packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 4.
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 "pdftops" filter converts Portable
Document Format (PDF) files to PostScript.
Multiple flaws were discovered in the CUPS "pdftops" filter. An attacker
could create a malicious PDF file that, when printed, would cause "pdftops"
to crash or, potentially, execute arbitrary code as the "lp" user.
(CVE-2010-3702, CVE-2009-3609)
Users of cups are advised to upgrade to these updated packages, which
