3. Description:

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)

Red Hat would like to thank the Apple Product Security team for responsibly
reporting these issues. Upstream acknowledges regenrecht as the original
reporter of CVE-2010-0542; Adrian 'pagvac' Pastor of GNUCITIZEN and Tim
Starling as the original reporters of CVE-2010-0540; and Luca Carettoni as
the original reporter of CVE-2010-1748.

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at

5. Bugs fixed (http://bugzilla.redhat.com/):

587746 - CVE-2010-0542 CUPS: texttops unchecked memory allocation failure leading to NULL pointer dereference
588805 - CVE-2010-0540 CUPS administrator web interface CSRF
