This doesn't seem to have been announced here: OpenSSL-0.9.6a appears
to have been released somewhat quietly, and also appears to include
several security fixes:
- Security fix: change behavior of OpenSSL to avoid using environment
variables when running as root.
=20
- Security fix: check the result of RSA-CRT to reduce the possibility
of deducing the private key from an incorrectly calculated signature.
=20
- Security fix: prevent Bleichenbacher's DSA attack.=20
=20
- Security fix: Zero the premaster secret after deriving the master
secret in DH ciphersuites.
Also:
We consider OpenSSL 0.9.6a to be the best version of OpenSSL
available and we strongly recommend that users of older versions,
especially of old SSLeay versions, upgrade as soon as possible.
