Immunix Secured OS Security Advisory
Packages updated: fileutils
Affected products: Immunix OS 7.0, 7+
Bugs fixed: CAN-2002-0435
Date: Fri May 16 2003
Advisory ID: IMNX-2003-7+-010-01
Author: Seth Arnold <sarnold@wirex.com>
-----------------------------------------------------------------------
Description:
Wojciech Purczynski discovered filesystem race conditions in the GNU
fileutils suite, that allows for local root compromise if root renames
or removes group- or world-writable directory trees.
This release fixes this problem by comparing (dev, inode) pairs before
and after chdir("..") calls. If the pairs don't match, an error is
returned. Thanks to Jim Meyering for the patch.
