Problem Description:
Due to improper handling of alert packets, OpenSSL would
consume an excessive amount of CPU time processing undefined
alert messages.
Impact:
A remote attacker who can initiate handshakes with an
OpenSSL based server can cause the server to consume a lot
of computation power with very little bandwidth usage, and
may be able to use this technique in a leveraged Denial of
Service attack.
