## Description

The IP implementation in Sun Solaris 8 through 10, and OpenSolaris before snv_82, uses an improper arena when allocating minor numbers for sockets, which allows local users to cause a denial of service (32-bit application failure and login outage) by opening a large number of sockets.

## What to do
