Clam AntiVirus is an open source (GPL) anti-virus toolkit for UNIX, |
| 40 |
designed especially for e-mail scanning on mail gateways. |

Nikolaos Rangos discovered a vulnerability in ClamAV which exists |
| 46 |
because the recipient address extracted from email messages is not |
| 47 |
properly sanitized before being used in a call to "popen()" when |
| 48 |
executing sendmail (CVE-2007-4560). Also, NULL-pointer dereference |
| 49 |
errors exist within the "cli_scanrtf()" function in libclamav/rtf.c and |
| 50 |
Stefanos Stamatis discovered a NULL-pointer dereference vulnerability |
| 51 |
within the "cli_html_normalise()" function in libclamav/htmlnorm.c |
| 52 |
(CVE-2007-4510). |
| 53 |
</p> |
| 54 |
</description> |
| 55 |
<impact type="high"> |
| 56 |
<p> |
| 57 |
The unsanitized recipient address can be exploited to execute arbitrary |
| 58 |
code with the privileges of the clamav-milter process by sending an |
| 59 |
email with a specially crafted recipient address to the affected |
| 60 |
system. Also, the NULL-pointer dereference errors can be exploited to |
| 61 |
crash ClamAV. Successful exploitation of the latter vulnerability |
| 62 |
requires that clamav-milter is started with the "black hole" mode |
| 63 |
activated, which is not enabled by default. |
| 64 |
</p> |
| 65 |
</impact> |
| 66 |
<workaround> |
| 67 |
<p> |
| 68 |
There is no known workaround at this time. |
| 69 |
</p> |
| 70 |
</workaround> |
| 71 |
<resolution> |
| 72 |
<p> |
| 73 |
All ClamAV users should upgrade to the latest version: |
| 74 |
</p> |
| 75 |
<code> |
| 76 |
# emerge --sync |
| 77 |
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.91.2"</code> |
| 78 |
</resolution> |
