Ubuntu 6.06 LTS / 6.10 / 7.04 : libexif vulnerability (USN-471-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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.

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 libexif-dev and / or libexif12 packages.

Risk factor :

High / CVSS Base Score : 9.3
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:C)
