Severity: High Title: UW IMAP toolkit: Multiple vulnerabilities Date: November 25, 2009 Bugs: #245425, #252567 ID: 200911-03

Synopsis ========
Multiple vulnerabilities have been found in the UW IMAP toolkit and the c-client library, the worst of which leading to the execution of arbitrary code.
Background ==========
The UW IMAP toolkit is a daemon for the IMAP and POP3 network mail protocols. The c-client library provides an API for IMAP, POP3 and other protocols.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-libs/c-client < 2007e >= 2007e 2 net-mail/uw-imap < 2007e >= 2007e ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
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.
Resolution ==========
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"
