Mandriva Linux Security Advisory 2010-196 - 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 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.

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).

Packages for 2009.1 were missing with the previous MDVSA-2009:242
update. This update corrects this.

This update provides a solution to this vulnerability.
