CUPS: Multiple vulnerabilities

Background

CUPS is the Common Unix Printing System.

Description

Several buffer overflows were found in:

• The read_rle16 function in imagetops (CVE-2008-3639, found by regenrecht, reported via ZDI)
• The WriteProlog function in texttops (CVE-2008-3640, found by regenrecht, reported via ZDI)

• The _cupsImageReadPNG function (CVE-2008-5286, reported by iljavs)

Impact

A remote attacker could send specially crafted input to a vulnerable server, resulting in the remote execution of arbitrary code with the privileges of the user running the server.

Workaround

None this time.

Resolution

All CUPS users should upgrade to the latest version.

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-print/cups-1.3.9-r1"
