The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. The CUPS &quot texttops&quot filter converts text files to PostScript. A missing memory allocation failure check flaw, leading to a NULL pointer dereference, was found in the CUPS &quot texttops&quot filter. An attacker could create a malicious text file that would cause &quot texttops&quot to crash or, potentially, execute arbitrary code as the &quot lp&quot 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.
