PNG library vulnerabilities

A security issue affects the following Ubuntu releases:

The following packages are affected:


The problem can be corrected by upgrading the affected package to version (libpng12-0 and libpng12-dev) or 1.0.15-6ubuntu1 (libpng10-0 and libpng10-dev). In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Several integer overflow vulnerabilities were discovered in the PNG library. These vulnerabilities could be exploited by an attacker by providing a specially crafted PNG image which, when processed by the PNG library, could result in the execution of program code provided by the attacker.

The PNG library is used by a variety of software packages for different purposes, so the exact nature of the exposure will vary depending on the software involved.
