Ubuntu Security Notice USN-2427-1
November 27, 2014

libksba vulnerability

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


Libksba could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- libksba: X.509 and CMS support library


Hanno Böck discovered that Libksba incorrectly handled certain S/MIME
messages or ECC based OpenPGP data. An attacker could use this issue to
cause Libksba to crash, resulting in a denial of service, or possibly execute
arbitrary code.

Update instructions:

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

Ubuntu 14.10:
  libksba8                        1.3.0-3ubuntu0.14.10.1

Ubuntu 14.04 LTS:
  libksba8                        1.3.0-3ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  libksba8                        1.2.0-2ubuntu0.1

In general, a standard system update will make all the necessary changes.
