Mandriva Linux Security Advisory MDVSA-2009:242-1
http://www.mandriva.com/security/
_______________________________________________________________________

Package : dovecot
Date : September 22, 2009
Affected: Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

A vulnerability was discovered and corrected in dovecot:

Multiple stack-based buffer overflows in the Sieve plugin in Dovecot
1.0 before 1.0.4 and 1.1 before 1.1.7, as derived from Cyrus libsieve,
allow context-dependent attackers to cause a denial of service
(crash) and possibly execute arbitrary code via a crafted SIEVE
script, as demonstrated by forwarding an e-mail message to a large
number of recipients, a different vulnerability than CVE-2009-2632
(CVE-2009-3235).

This update provides a solution to this vulnerability.

Update:

Packages for Enterprise 5 i586 were missing with the previous
update. This update corrects this.
