Ubuntu 6.06 LTS / 8.04 LTS / 9.10 / 10.04 LTS / 10.10 : postfix vulnerabilities (USN-1113-1)

medium Nessus Plugin ID 55071

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that the Postfix package incorrectly granted write access on the PID directory to the postfix user. A local attacker could use this flaw to possibly conduct a symlink attack and overwrite arbitrary files. This issue only affected Ubuntu 6.06 LTS and 8.04 LTS. (CVE-2009-2939)

Wietse Venema discovered that Postfix incorrectly handled cleartext commands after TLS is in place. A remote attacker could exploit this to inject cleartext commands into TLS sessions, and possibly obtain confidential information such as passwords. (CVE-2011-0411).

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 postfix package.
