(RHSA-2010:0755) Important: cups security update

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
contain backported patches to correct these issues. After installing this
update, the cupsd daemon will be restarted automatically.
