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

critical Nessus Plugin ID 42913

Synopsis

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

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).
Ludwig 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.

Solution

All c-client library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-libs/c-client-2007e' All UW IMAP toolkit users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/uw-imap-2007e'
