ClamAV < 0.97.8 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 6782

Synopsis

The remote host is running an anti-virus application that is affected by multiple vulnerabilities.

Description

Versions of ClamAV earlier than 0.97.8 are potentially affected by the following vulnerabilities :

- An overflow condition in 'libclamav/pdf.c' may be triggered as user-supplied input is not properly validated when handling a specially crafted encrypted PDF file. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2013-2021)

- An overflow condition in 'libclamav/pe.c' may be triggered as user-supplied input is not properly validated when handling a specially crafted UPX-packed executable file. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2013-2020)

Solution

Upgrade to ClamAV 0.97.8 or later.
