"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.

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."
