Ubuntu Security Notice (C) 2004-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
A buffer overflow was discovered in the TIFF library. A TIFF file
includes a value indicating the number of 'directory entry' header
fields contained in the file. If this value is -1, an invalid memory
allocation was performed. A malicious image could be constructed
which, when decoded, would have resulted in execution of arbitrary
code with the privileges of the process using the library.
Since this library is used in many applications like 'ghostscript' and
the 'CUPS' printing system, this vulnerability may lead to remotely
induced privilege escalation.
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.
Update the affected libtiff-tools, libtiff4 and / or libtiff4-dev
