Nikolaos Rangos discovered a vulnerability in ClamAV which exists
|
|
because the recipient address extracted from email messages is not
|
|
properly sanitized before being used in a call to "popen()" when
|
|
executing sendmail (CVE-2007-4560). Also, NULL-pointer dereference
|
|
errors exist within the "cli_scanrtf()" function in libclamav/rtf.c and
|
|
Stefanos Stamatis discovered a NULL-pointer dereference vulnerability
|
|
within the "cli_html_normalise()" function in libclamav/htmlnorm.c
|
|
(CVE-2007-4510).
|

<impact type="high">
|
|
<p>
|
|
The unsanitized recipient address can be exploited to execute arbitrary
|
|
code with the privileges of the clamav-milter process by sending an
|
|
email with a specially crafted recipient address to the affected
|
|
system. Also, the NULL-pointer dereference errors can be exploited to
|
|
crash ClamAV. Successful exploitation of the latter vulnerability
|
|
requires that clamav-milter is started with the "black hole" mode
|
|
activated, which is not enabled by default.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ClamAV users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.91.2"</code>
|
|
</resolution>
