This also "reverts" some FreeBSD local changes so we should now
be back to using entirely stock OpenSSL. The local changes were
simple $FreeBSD$ lines additions, which were required in the CVS
days, and the patch for FreeBSD-SA-09:15.ssl which has been
superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation
extension' support.
MFC after: 3 weeks
From the OpenSSL advisory:
Andy Polyakov discovered a flaw in OpenSSL's DTLS
implementation which could lead to the compromise of clients
and servers with DTLS enabled.
DTLS is a datagram variant of TLS specified in RFC 4347 first
supported in OpenSSL version 0.9.8. Note that the
vulnerabilities do not affect SSL and TLS so only clients and
servers explicitly using DTLS are affected.
We believe this flaw will permit remote code execution.
