Severity:	high
Title:	CUPS: Multiple vulnerabilities
Date:	12/10/2008
Bugs:	#238976, #249727
ID:	200812-11

Synopsis

Several remotely exploitable bugs have been found in CUPS, which allow remote execution of arbitrary code.

Background

CUPS is the Common Unix Printing System.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-print/cups	< 1.3.9-r1	>= 1.3.9-r1	All supported architectures

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 Hewlett-Packard Graphics Language (HPGL) filter (CVE-2008-3641, found by regenrecht, reported via iDefense)
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"
