Synopsis
========

Multiple vulnerabilities have been discovered in libpng which can allow
a remote attacker to cause a Denial of Service condition.

Background
==========

libpng is a standard library used to process PNG (Portable Network
Graphics) images. It is used by several programs, including web
browsers and potentially server processes.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libpng < 1.6.10 >= 1.6.10
< 1.3
*>= 1.5.18

Description
===========

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.

Resolution
==========

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.
