high Nessus Plugin ID 136533

Language:

Synopsis

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

Description

Requests to create cryptography sessions using a MAC did not validate the user-supplied MAC key length. The cryptodev module allocates a buffer whose size is this user-suppled length. Impact : An unprivileged process can trigger a kernel panic.

Solution

Update the affected package.
