[RHSA-2004:344-01] Updated semi packages fix flim vulnerability

Wed Aug 18 15:39:00 UTC 2004

Updated semi packages that fix vulnerabilities in flim temporary file
handling are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - noarch
Red Hat Linux Advanced Workstation 2.1 - noarch
Red Hat Enterprise Linux ES version 2.1 - noarch
Red Hat Enterprise Linux WS version 2.1 - noarch

3. Problem description:

The semi package includes a MIME library for GNU Emacs and XEmacs used by
the wl mail package.

Tatsuya Kinoshita discovered a vulnerability in flim, an emacs library
for working with Internet messages included in the semi package. Temporary
files were being created without taking adequate precautions, and therefore
a local user could potentially overwrite files with the privileges of the
user running emacs.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0422 to this issue.

Users of semi are advised to upgrade to these packages, which contain
a backported patch fixing this issue.
