RHSA-2009:0429: Important security update
35
This update has been rated as having important security impact by the Red Hat Security Response
Team.
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
208
,
CVE-2009-1179
209
)
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
210
,
CVE-2009-1182
211
)
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
212
,
CVE-2009-1180
213
)
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
214
)
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
215
)
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
216
,
CVE-2009-1181
217
,
CVE-2009-1183
218
)
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.
