Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : libpng vulnerability (USN-1402-1)

Medium Nessus Plugin ID 58443


The remote Ubuntu host is missing a security-related patch.


It was discovered that libpng did not properly process compressed chunks. 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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libpng12-0 package.
