medium Nessus Plugin ID 66308
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The antivirus service running on the remote host is affected by multiple vulnerabilities.

Description

According to its version, the ClamAV clamd antivirus daemon on the remote host is earlier than 0.97.8 and is, therefore, potentially affected by the following vulnerabilities :

- An overflow condition exists in the 'getsisstring()' function in 'libclamav/sis.c' when handling SIS content.
This flaw reportedly only affects GNU/Linux.
(Issue 6808)

- A heap overflow exists in the 'libclamav/pdf.c' when handling a specially crafted encrypted PDF file. This flaw reportedly affects ClamAV 0.97.1 - 0.97.7 only.
(Issue 7053)

- A heap overflow exists in 'libclamav/pe.c' that is triggered when handling a specially crafted UPX-packed executable. (Issue 7055)

Solution

Upgrade to ClamAV 0.97.8 or later.
