Immunix Secured OS Security Advisory
Packages updated: fetchmail, fetchmailconf
Affected products: Immunix OS 7+
Bugs fixed: CAN-2002-1365, CAN-2003-0792, CAN-2003-0790
Date: Fri Oct 17 2003
Advisory ID: IMNX-2003-7+-023-01
Author: Seth Arnold <sarnold@xxxxxxxxxxx>
-----------------------------------------------------------------------
Description:
This update fixes several bugs in fetchmail, including a broken
boundary condition check in the multidrop code, a header overflow that
neglected to account for '@' signs in email addresses (CAN-2002-1365),
a header-rewriting bug (CAN-2003-0792), and a head-reading bug
(CAN-2003-0790; this CAN is likely to be revoked, but the patch appears
to be nicely defensive).
Immunix would like to thank Stefan Esser, Dave Jones, Markus Friedl,
Nalin Dahyabhai, Mark J Cox, and Eric S. Raymond for diagnosing and
fixing the problems.
It is unknown if any of these problems lead to more than a Denial of
Service attack. We do not believe StackGuard provides protection for
any of the bugs addressed here.
