cupsys - multiple vulnerabilities

Several local/remote vulnerabilities have been discovered in cupsys, the
Common Unix Printing System. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2008-0047

Heap-based buffer overflow in CUPS, when printer sharing is enabled,
allows remote attackers to execute arbitrary code via crafted search
expressions.

• CVE-2008-0882

Double free vulnerability in the process_browse_data function in CUPS
1.3.5 allows remote attackers to cause a denial of service (daemon
crash) and possibly the execution of arbitrary code via crafted packets to the
cupsd port (631/udp), related to an unspecified manipulation of a
remote printer.

For the stable distribution (etch), these problems have been fixed in
version 1.2.7-4etch3.

We recommend that you upgrade your cupsys packages.
