Synopsis

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

Description

Due to insufficient validation of the SCTP stream ID, which serves as an array index, a local unprivileged attacker can read or write 16-bits of kernel memory. Impact : An unprivileged process can read or modify 16-bits of memory which belongs to the kernel. This may lead to exposure of sensitive information or allow privilege escalation.

Solution

Update the affected packages.
