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

45 |
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 |

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> |
