Synopsis :

Description :

It was discovered that libpng did not properly initialize memory when
decoding certain 1-bit interlaced images. If a user or automated
system were tricked into processing crafted PNG images, an attacker
could possibly use this flaw to read sensitive information stored in
memory. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 8.10 and
9.04. (CVE-2009-2042)

It was discovered that libpng did not properly handle certain
excessively compressed PNG images. If a user or automated system were
tricked into processing a crafted PNG image, an attacker could
possibly use this flaw to consume all available resources, resulting
in a denial of service. (CVE-2010-0205).

Solution :

Update the affected libpng12-0, libpng12-dev and / or libpng3
packages.
