    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.
    
    Upgrade Instructions
