critical Nessus Plugin ID 65668
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 0.97.7 and is, therefore, potentially affected by the following vulnerabilities :

- A memory access error exists related to the function 'check_user_password' and debug-printing that could access 32 bytes rather than the proper 16 bytes.
(Issue 6804 / CVE-2013-7089)

- A heap-corruption error exists in the function 'wwunpack' in the file 'libclamav/wwunpack.c' related to unpacking 'WWPack' files. (Issue 6806 / CVE-2013-7087)

- An unspecified overflow error exists related to 'y0da' emulation that could result in application crashes or other unspecified impact. (Issue 6809 / CVE-2013-7088)

- A double-free error exists in the function 'unrar_extract_next_prepare' in the file 'libclamunrar_iface/unrar_iface.c' related to handling 'RAR' files.

Solution

Upgrade to ClamAV 0.97.7 or later.
