Ubuntu 4.10 / 5.04 / 5.10 : netpbm-free vulnerabilities (USN-218-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Two buffer overflows were discovered in the 'pnmtopng' tool, which
were triggered by processing an image with exactly 256 colors when
using the -alpha option (CVE-2005-3662) or by processing a text file
with very long lines when using the -text option (CVE-2005-3632).

A remote attacker could exploit these to execute arbitrary code by
tricking an user or an automated system into processing a specially
crafted PNM file with pnmtopng.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 4.6
(CVSS2#AV:L/AC:L/Au:N/C:P/I:P/A:P)
