Synopsis

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

Description

According to its version, the ClamAV clamd antivirus daemon running on the remote host is prior to 0.99.2. It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists in the libclamav library when handling specially crafted mew packer executables. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to crash the application.
(CVE-2016-1371)

- Multiple denial of service vulnerabilities exist in the libclamav library when handling specially crafted 7z files. An unauthenticated, remote attacker can exploit these, by convincing a user to open a specially crafted file, to crash the application. (CVE-2016-1372)

Solution

Upgrade to ClamAV version 0.99.2 or later.
