ClamAV < 0.98.5 Multiple Vulnerabilities

Medium

Synopsis

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

Description

Versions of ClamAV earlier than 0.98.5 are potentially affected by the following vulnerabilities :

- A flaw in the 'clamscan -a' command may cause a denial of service. The issue is triggered when a user opens a malformed JavaScript or Yoda Crypter file, resulting in a loss of availability of the program. (CVE-2013-6497)

- An overflow condition in the 'cli_scanpe()' function in 'libclamav/pe.c' may be triggered as user-supplied input is not properly validated when scanning a specially crafted Yoda Crypter file potentially allowing a remote attacker to cause a heap-based buffer overflow resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2013-9050)

Solution

Upgrade to ClamAV 0.98.5 or later.
