Package        : semi, wemi
Vulnerability  : insecure temporary file
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0440

semi, a MIME library for GNU Emacs, does not take appropriate
security precautions when creating temporary files.  This bug could
potentially be exploited to overwrite arbitrary files with the
privileges of the user running Emacs and semi, potentially with
contents supplied by the attacker.

wemi is a fork of semi, and contains the same bug.

For the stable distribution (woody) this problem has been fixed in
semi version 1.14.3.cvs.2001.08.10-1woody2 and wemi version
1.14.0.20010802wemiko-1.3.

For the unstable distribution (sid) this problem has been fixed in
semi version 1.14.5+20030609-1.  The unstable distribution does not
contain a wemi package.

We recommend that you update your semi and wemi packages.
