The remote host is missing updates announced in
advisory RHSA-2008:0937.
The Common UNIX Printing System (CUPS) provides a portable printing layer
for UNIX(R) operating systems.
A buffer overflow flaw was discovered in the SGI image format decoding
routines used by the CUPS image converting filter imagetops. An attacker
could create a malicious SGI image file that could, possibly, execute
arbitrary code as the lp user if the file was printed. (CVE-2008-3639)
An integer overflow flaw leading to a heap buffer overflow was discovered
in the Text-to-PostScript texttops filter. An attacker could create a
malicious text file that could, possibly, execute arbitrary code as the
lp user if the file was printed. (CVE-2008-3640)
An insufficient buffer bounds checking flaw was discovered in the
HP-GL/2-to-PostScript hpgltops filter. An attacker could create a
malicious HP-GL/2 file that could, possibly, execute arbitrary code as the
lp user if the file was printed. (CVE-2008-3641)
Red Hat would like to thank regenrecht for reporting these issues.
All CUPS users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
