USN-130-1: TIFF library vulnerability

20 May 2005

tiff vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 5.04
  • Ubuntu 4.10

Software Description

Details

Tavis Ormandy discovered a buffer overflow in the TIFF library. A malicious image with an invalid “bits per sample” number 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 5.04
libtiff4
Ubuntu 4.10
libtiff4

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
