Medium Nessus Plugin ID 28145


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that libpng did not properly perform bounds checking and comparisons in certain operations. An attacker could send a specially crafted PNG image and cause a denial of service in applications linked against libpng.

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, libpng12-dev and / or libpng3 packages.
