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.


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


Versions of ClamAV earlier than 0.97.7 are 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)

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

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

- 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
