Ubuntu Security Notice 1367-1 - 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. 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. Various other issues were also addressed.
