GLSA-200709-14 : ClamAV: Multiple vulnerabilities

High Nessus Plugin ID 26104


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200709-14 (ClamAV: Multiple vulnerabilities)

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 :

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.
Workaround :

There is no known workaround at this time.


All ClamAV users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-antivirus/clamav-0.91.2'
