Ubuntu 4.10 / 5.04 / 5.10 : fetchmail vulnerability (USN-215-1)

Low Nessus Plugin ID 20633


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


Thomas Wolff and Miloslav Trmac discovered a race condition in the fetchmailconf program. The output configuration file was initially created with insecure permissions, and secure permissions were applied after writing the configuration into the file. During this time, the file was world readable on a standard system (unless the user manually tightened his umask setting), which could expose email passwords to local users.

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 fetchmail, fetchmail-ssl and / or fetchmailconf packages.
