-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : postfix SUMMARY : Possivble remote DoS DATE : 2001-11-26 15:47:00 ID : CLA-2001:439 RELEVANT RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- 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.
