Subject: [USN-46-1] TIFF library vulnerability

===========================================================
Ubuntu Security Notice USN-46-1		  December 22, 2004
tiff vulnerability
CAN-2004-1308
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libtiff4

The problem can be corrected by upgrading the affected package to
version 3.6.1-1.1ubuntu1.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

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.
