In OpenSSL-1.0.1f, in 'ssl3_send_server_key_exchange' function, when all the below conditions are true, there is a potential memory leak. 1) 'type SSL_kEECDH' is true, (ie the key exchange is ephemeral ecdh) 2) 'ecdhp == NULL' 's-cert-ecdh_tmp_cb != NULL' 3) 's-cert-ecdh_tmp_cb' mallocs a new

Generation ECDHE parameters

2012-08-22 Thread Varma Dantuluri
Hi We are in the process of adding support for ECDSA-ECDHE cipher suites and hence ECDSA certificates to our server. Right now, the server does the following: 1) Assign the ECDSA certificate to the SSL_CTX. 2) Set the callback for ECDH parameter generation using SSL_CTX_set_tmp_ecdh_callback.

Use of X_FLAG_NON_FIPS_ALLOW flag in FIPS Module 2.0

OpenSSL 1.0.1 has the following flag definitions: RSA_FLAG_NON_FIPS_ALLOW DSA_FLAG_NON_FIPS_ALLOW EC_FLAG_NON_FIPS_ALLOW EVP_CIPH_FLAG_NON_FIPS_ALLOW EVP_MD_CTX_FLAG_NON_FIPS_ALLOW And these flags are checked in either the FIPS Module 2.0 code itself (fipscanister.o) or in the FIPS capable

Thanks Steve. Just curious as to why this cannot be done. Is it because of some structure changes between 0.9.8 and 1.0.1? Thanks Varma On Tue, Dec 6, 2011 at 7:25 AM, Steve Marquess marqu...@opensslfoundation.com wrote: On 12/05/2011 08:39 PM, Varma Dantuluri wrote: Hi Can the new

Hi Can the new OpenSSL FIPS 2.0 module be used with OpenSSL 0.9.8 releases? Or can it only be used with OpenSSL 1.0.1 and later? Thanks Varma
