    Vulnerability  : insecure temporary files
    Problem-Type   : local
    Debian-specific: no
    
    Paul Szabo discovered bugs in three scripts included in the sendmail
    package where temporary files were created insecurely (expn,
    checksendmail and doublebounce.pl).  These bugs could allow an
    attacker to gain the privileges of a user invoking the script
    (including root).
    
    For the stable distribution (woody) these problems have been fixed in
    version 8.12.3-6.4.
    
    For the old stable distribution (potato) these problems have been fixed
    in version 8.9.3-26.1.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 8.12.9-2.
    
    We recommend that you update your sendmail package.
    
    Upgrade Instructions
