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 remote FreeBSD host is missing one or more security-related updates.

Description

A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers.
Impact : An attacker in control of the URL to be fetched (possibly via HTTP redirect) may cause a heap buffer overflow, resulting in program misbehavior or malicious code execution.

Solution

Update the affected packages.
