SUMMARY   : Possivble remote DoS
DATE      : 2001-11-26 15:47:00

DESCRIPTION
 Postfix is a widely used MTA (Mail Transport Agent, sometimes called
 just an email or SMTP server).
 
 Wietse Venema reported[1] a vulnerability[2] in Postfix where a
 remote attacker could cause a DoS (denial of service) condition on
 the server. The SMTP session log could grow to an unreasonable size
 and possibly exhaust the server's memory if no other limits were in
 place.


SOLUTION
 It is recommended that all Postfix users upgrade their servers.
