Title: libpng: Information disclosure
Date: June 27, 2009
Bugs: #272970
ID: 200906-01
Synopsis
=======
A vulnerability has been discovered in libpng that allows for
information disclosure.
Background
=========
libpng is the official PNG reference library used to read, write and
manipulate PNG images.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libpng < 1.2.37 >= 1.2.37
==========
Jeff Phillips discovered that libpng does not properly parse 1-bit
interlaced images with width values that are not divisible by 8, which
causes libpng to include uninitialized bits in certain rows of a PNG
file.
Impact
=====
A remote attacker might entice a user to open a specially crafted PNG
file, possibly resulting in the disclosure of sensitive memory
portions.
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-1.2.37"
