CVE-2011-1929

TITLE

Dovecot of lib-mail/message-header-parser.c Service disruption in (DoS) Vulnerabilities

DESCRIPTION

lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message. Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like systems. Dovecot is prone to a denial-of-service vulnerability because it fails to properly parse message headers. A remote attacker can exploit this issue to crash the affected application, denying service to legitimate users. Dovecot versions prior to 1.2.17 and 2.0.13 are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: dovecot security update Advisory ID: RHSA-2011:1187-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1187.html Issue date: 2011-08-18 CVE Names: CVE-2011-1929 ===================================================================== 1.
