FreeBSD : suricata -- buffer over-read (3b903bf3-7f94-11e9-8a5f-c85b76ce9b5a)

critical Nessus Plugin ID 125439

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Mitre reports :

An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \r results in an integer underflow.

Solution

Update the affected package.
