Test ID:1.3.6.1.4.1.25623.1.0.70842
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-1131-1 (postfix)
Summary:Ubuntu USN-1131-1 (postfix)
Description:The remote host is missing an update to postfix
announced via advisory USN-1131-1.

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.

Solution:
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
