Details

It was discovered that libpng did not properly verify the embedded profile
length of iCCP chunks. An attacker could exploit this to cause a denial of
service via application crash. This issue only affected Ubuntu 8.04 LTS.
(CVE-2009-5063)

Jueri Aedla discovered that libpng did not properly verify the size used
when allocating memory during chunk decompression. If a user or automated
system using libpng were tricked into opening a specially crafted image,
an attacker could exploit this to cause a denial of service or execute
code with the privileges of the user invoking the program. (CVE-2011-3026)
