ClamAV < 0.97.8 Multiple Vulnerabilities

medium Nessus Plugin ID 66308

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.
