high Nessus Plugin ID 27866

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

A Denial of Service vulnerability has been found in the function for encoding email addresses. Addresses containing a '=' before the '@' character caused the Courier to hang in an endless loop, rendering the service unusable.

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.
