Ubuntu 4.10 : libgd vulnerabilities (USN-33-1)

Ubuntu Security Notice (C) 2004-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

CAN-2004-0990 described several buffer overflows which had been
discovered in libgd's PNG handling functions. Another update is
required because the update from USN-21-1 was not sufficient to
prevent every possible attack.

If an attacker tricks a user into loading a malicious PNG or XPM
image, they could leverage this into executing arbitrary code in the
context of the user opening image.

This vulnerability might lead to privilege escalation in customized
systems that use server applications which link libgd. However, Warty
does not ship such server applications (PHP in Warty uses libgd2 which
was already fixed in USN-25-1).

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
