Ubuntu 11.10 : dovecot vulnerability (USN-1295-1)

Medium Nessus Plugin ID 57059


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


It was discovered that Dovecot incorrectly validated certificate hostnames when being used as a POP3 and IMAP proxy. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information.

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.


Update the affected dovecot-common package.
