Mandrake Linux Security Advisory : fetchmail (MDKSA-2005:209)
Medium Nessus Plugin ID 20442
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionThomas Wolff and Miloslav Trmac discovered a race condition in the fetchmailconf program. fetchmailconf would create the initial output configuration file with insecure permissions and only after writing would it change permissions to be more restrictive. During that time, passwords and other data could be exposed to other users on the system unless the user used a more restrictive umask setting.
As well, the Mandriva Linux 2006 packages did not contain the patch that corrected the issues fixed in MDKSA-2005:126, namely a buffer overflow in fetchmail's POP3 client (CVE-2005-2355).
The updated packages have been patched to address this issue, and the Mandriva 2006 packages have also been patched to correct CVE-2005-2355.
SolutionUpdate the affected fetchmail, fetchmail-daemon and / or fetchmailconf packages.
