From: Jim Knoble <jmknoble@jmknoble.cx> To: BUGTRAQ@SECURITYFOCUS.COM Subject: OpenSSL-0.9.6a has security fixes Date: Tue, 24 Apr 2001 15:40:07 -0400 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. - Security fix: check the result of RSA-CRT to reduce the possibility of deducing the private key from an incorrectly calculated signature. - Security fix: prevent Bleichenbacher's DSA attack. - 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.
