    A security problem has been discovered in getmail, a POP3 and APOP
    mail gatherer and forwarder.  An attacker with a shell account on the
    victims host could utilise getmail to overwrite arbitrary files when
    it is running as root.
    
    For the stable distribution (woody) this problem has been fixed in
    version 2.3.7-2.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 3.2.5-1.
    
    We recommend that you upgrade your getmail package.
