Ubuntu 6.06 LTS / 8.04 LTS / 10.04 LTS / 10.10 / 11.04 : postfix vulnerability (USN-1131-1)
Medium Nessus Plugin ID 55092
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionThomas 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.
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.
SolutionUpdate the affected postfix package.
