    PACKAGE : exim
    SUMMARY : Remote buffer overflow vulnerability
    DATE : 2003-09-05 15:11:00
    ID : CLA-2003:735
    RELEVANT
    RELEASES : 7.0, 8, 9

    DESCRIPTION
     Exim[1] is a popular email server (MTA).
     
     A remote heap buffer overflow vulnerability[2] has been reported[3]
     in the Exim server. Carefully constructed EHLO/HELO messages can
     cause a buffer overflow. By the time this message is processed, Exim
     is no longer running with administrator privileges. At this time,
     this vulnerability is believed to be difficult to exploit.
     
     Exim is not installed nor started by default on Conectiva Linux.

    SOLUTION
     It is recommended that all Exim users upgrade their packages. After
     the upgrade, Exim will be automatically restarted if it was already
     running.
