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.
