medium Nessus Plugin ID 134723

Synopsis

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

Description

The driver-specific ioctl(2) command handlers in ixl(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation. Impact : The ixl(4) handler permits unprivileged users to trigger updates to the device's non-volatile memory (NVM).

Solution

Update the affected package.
