"A potential buffer overflow has been found in the xpdf viewer. An
insufficient input validation could be exploited by an attacker
providing a specially crafted PDF file which, when processed by xpdf,
could result in abnormal program termination or the execution of
attacker supplied program code with the user's privileges.

The tetex-bin package contains the affected xpdf code to generate PDF
output and process included PDF files, thus is vulnerable as well.

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."
