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

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 CVE-2004-0422 to this issue.

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