<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.

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.

Multiple vulnerabilities were found in the UW IMAP toolkit:
|
|
</p>
|
|
<ul>
|
|
<li>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).</li>
|
|
<li>An error in smtp.c in the c-client library was found, leading to a
|
|
NULL pointer dereference vulnerability (CVE-2008-5006).</li>
|
|
<li>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).</li>
|
|
</ul>

<impact type="high">
|
|
<p>
|
|
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.

All c-client library users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-libs/c-client-2007e"</code>
