Description

An integer overflow has been discovered in the FreeType library. By tricking a user into installing and/or opening a specially crafted font file, these could be exploited to execute arbitrary code with the privileges of that user.

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.
