Ubuntu 4.10 : xpdf, cupsys vulnerabilities (USN-64-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

A buffer overflow has been found in the xpdf viewer. An insufficient
input validation of the encryption key length 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 Common UNIX Printing System (CUPS) uses the same code to print PDF
files. In this case, this bug could be exploited to gain the
privileges of the CUPS print server (by default, user cupsys).

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.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
