3. Description:
The Common UNIX® Printing System (CUPS) provides a portable printing layer
for UNIX operating systems.
Multiple integer overflow flaws were found in the CUPS JBIG2 decoder. An
attacker could create a malicious PDF file that would cause CUPS to crash
or, potentially, execute arbitrary code as the "lp" user if the file was
printed. (CVE-2009-0147, CVE-2009-1179)
Multiple buffer overflow flaws were found in the CUPS JBIG2 decoder. An
attacker could create a malicious PDF file that would cause CUPS to crash
or, potentially, execute arbitrary code as the "lp" user if the file was
printed. (CVE-2009-0146, CVE-2009-1182)
Multiple flaws were found in the CUPS JBIG2 decoder that could lead to the
freeing of arbitrary memory. An attacker could create a malicious PDF file
that would cause CUPS to crash or, potentially, execute arbitrary code
as the "lp" user if the file was printed. (CVE-2009-0166, CVE-2009-1180)
Multiple input validation flaws were found in the CUPS JBIG2 decoder. An
attacker could create a malicious PDF file that would cause CUPS to crash
or, potentially, execute arbitrary code as the "lp" user if the file was
printed. (CVE-2009-0800)
An integer overflow flaw, leading to a heap-based buffer overflow, was
discovered in the Tagged Image File Format (TIFF) decoding routines used by
the CUPS image-converting filters, "imagetops" and "imagetoraster". An
attacker could create a malicious TIFF file that could, potentially,
execute arbitrary code as the "lp" user if the file was printed.
(CVE-2009-0163)
Multiple denial of service flaws were found in the CUPS JBIG2 decoder. An
attacker could create a malicious PDF file that would cause CUPS to crash
when printed. (CVE-2009-0799, CVE-2009-1181, CVE-2009-1183)
Red Hat would like to thank Aaron Sigel, Braden Thomas and Drew Yao of
the Apple Product Security team, and Will Dormann of the CERT/CC for
responsibly reporting these flaws.
Users of cups are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
update, the cupsd daemon will be restarted automatically.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
