Description

NOTE: due to a combination of administrative problems, this advisory was erroneously released with the identifier 'DSA-337-1'. DSA-337-1 correctly refers to an earlier advisory regarding gtksee.

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.
