Test ID:1.3.6.1.4.1.25623.1.0.59160
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-471-1 (libexif)
Summary:Ubuntu USN-471-1 (libexif)
Description:
The remote host is missing an update to libexif
announced via advisory USN-471-1.

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

Details follow:

Victor Stinner discovered that libexif did not correctly validate the
size of some EXIF header fields. By tricking a user into opening an
image with specially crafted EXIF headers, a remote attacker could cause
the application using libexif to crash, resulting in a denial of service.

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

Ubuntu 6.06 LTS:
libexif12 0.6.12-2ubuntu0.1

Ubuntu 6.10:
libexif12 0.6.13-4ubuntu0.1

Ubuntu 7.04:
libexif12 0.6.13-5ubuntu0.1

After a standard system upgrade you need to restart your session to
effect the necessary changes.
