Software Description: - postfix: High-performance mail transport agent Details: Thomas Jarosch discovered that Postfix incorrectly handled authentication mechanisms other than PLAIN and LOGIN when the Cyrus SASL library is used. A remote attacker could use this to cause Postfix to crash, leading to a denial of service, or possibly execute arbitrary code as the postfix user. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: postfix 2.8.2-1ubuntu2.1 Ubuntu 10.10: postfix 2.7.1-1ubuntu0.2 Ubuntu 10.04 LTS: postfix 2.7.0-1ubuntu0.2 Ubuntu 8.04 LTS: postfix 2.5.1-2ubuntu1.4 Ubuntu 6.06 LTS: postfix 2.2.10-1ubuntu0.4 In general, a standard system update will make all the necessary changes.
