==========================================================================
Ubuntu Security Notice USN-1436-1
May 02, 2012

libtasn1-3 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Libtasn1 could be made to crash or run programs as your login if it
received specially crafted input.

Software Description:
- libtasn1-3: Library to manage ASN.1 structures

Details:

Matthew Hall discovered that Libtasn1 incorrectly handled certain large
values. An attacker could exploit this with a specially crafted ASN.1
structure and cause 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 12.04 LTS:
  libtasn1-3                      2.10-1ubuntu1.1

Ubuntu 11.10:
  libtasn1-3                      2.9-4ubuntu0.1

Ubuntu 11.04:
  libtasn1-3                      2.7-1ubuntu1.1

Ubuntu 10.04 LTS:
  libtasn1-3                      2.4-1ubuntu0.1

Ubuntu 8.04 LTS:
  libtasn1-3                      1.1-1ubuntu0.1

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