The remote host is missing updates announced in
advisory RHSA-2008:0192.
The Common UNIX Printing System (CUPS) provides a portable printing layer
for UNIX(R) operating systems.
A heap buffer overflow flaw was found in a CUPS administration interface
CGI script. A local attacker able to connect to the IPP port (TCP port 631)
could send a malicious request causing the script to crash or, potentially,
execute arbitrary code as the lp user. Please note: the default CUPS
configuration in Red Hat Enterprise Linux 5 does not allow remote
connections to the IPP TCP port. (CVE-2008-0047)
Red Hat would like to thank regenrecht for reporting this issue.
This issue did not affect the versions of CUPS as shipped with Red Hat
Enterprise Linux 3 or 4.
Two overflows were discovered in the HP-GL/2-to-PostScript filter. An
attacker could create a malicious HP-GL/2 file that could possibly execute
arbitrary code as the lp user if the file is printed. (CVE-2008-0053)
A buffer overflow flaw was discovered in the GIF decoding routines used by
CUPS image converting filters imagetops and imagetoraster. An attacker
could create a malicious GIF file that could possibly execute arbitrary
code as the lp user if the file was printed. (CVE-2008-1373)
All cups users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
