This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-201408-06
(libpng: Multiple vulnerabilities)

The png_push_read_chunk function in pngpread.c in the progressive
decoder enters an infinite loop, when it encounters a zero-length IDAT
chunk. In addition certain integer overflows have been detected and
corrected.
The 1.2 branch is not affected by these vulnerabilities.

Impact :

A remote attacker could entice a user to open a specially crafted PNG
file using an application linked against libpng, possibly resulting in
Denial of Service.

Workaround :

There is no known workaround at this time.

Solution :

All libpng users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/libpng-1.6.10'
Users with current installs in the 1.5 branch should also upgrade this
using:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/libpng-1.5.18:1.5'
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
