The Common UNIXÂ® Printing System (CUPS) provides a portable printing
layer for UNIX operating systems. The Internet Printing Protocol (IPP)
allows users to print and manage printing-related tasks over a
network. The CUPS 'pdftops' filter converts Portable Document Format
(PDF) files to PostScript. 'pdftops' is based on Xpdf and the CUPS
A NULL pointer dereference flaw was found in the CUPS IPP routine,
used for processing incoming IPP requests for the CUPS scheduler. An
attacker could use this flaw to send specially crafted IPP requests
that would crash the cupsd daemon. (CVE-2009-0949)
A use-after-free flaw was found in the CUPS scheduler directory
services routine, used to process data about available printers and
printer classes. An attacker could use this flaw to cause a denial of
service (cupsd daemon stop or crash). (CVE-2009-1196)
Multiple integer overflows flaws, leading to heap-based buffer
overflows, were found in the CUPS 'pdftops' filter. An attacker could
create a malicious PDF file that would cause 'pdftops' to crash or,
potentially, execute arbitrary code as the 'lp' user if the file was
Red Hat would like to thank Anibal Sacco from Core Security
