GLSA-200911-03 : UW IMAP toolkit: Multiple vulnerabilities

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200911-03
(UW IMAP toolkit: Multiple vulnerabilities)

Multiple vulnerabilities were found in the UW IMAP toolkit:
Aron Andersson and Jan Sahlin of Bitsec reported boundary errors in
the 'tmail' and 'dmail' utilities when processing overly long mailbox
names, leading to stack-based buffer overflows (CVE-2008-5005).
An error in smtp.c in the c-client library was found, leading to a
NULL pointer dereference vulnerability (CVE-2008-5006).
Nussel reported an off-by-one error in the rfc822_output_char()
function in the RFC822BUFFER routines in the c-client library, as used
by the UW IMAP toolkit (CVE-2008-5514).

Impact :

A remote attacker could send an e-mail to a destination mailbox name
composed of a username and '+' character followed by a long string,
possibly leading to the execution of arbitrary code. A local attacker
could gain privileges by specifying a long folder extension argument to
the tmail or dmail program. Furthermore, a remote attacker could send a
specially crafted mail message to the UW IMAP toolkit or another daemon
using the c-client library, leading to a Denial of Service. A remote
SMTP server could respond to the QUIT command with a close of the TCP
connection instead of the expected 221 response code, possibly leading
to a Denial of Service.

Workaround :

There is no known workaround at this time.
