Subject: [ruby-changes:43862] usa:r55935 (ruby_2_2): merge revision(s) 55175: [Backport #12428]
usa 2016-08-16 20:33:35 +0900 (Tue, 16 Aug 2016) New Revision: 55935 https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=55935 Log: merge revision(s) 55175: [Backport #12428] * ext/openssl/ossl_pkey_dh.c (ossl_dh_compute_key): Check that the DH has 'p' (the prime) before calling DH_size(). We can create a DH with no parameter but DH_size() does not check and dereferences NULL. [ruby-core:75720] [Bug #12428] * ext/openssl/ossl_pkey_dsa.c (ossl_dsa_sign): Ditto. DSA_size() does not check dsa->q. * ext/openssl/ossl_pkey_rsa.c (ossl_rsa_public_encrypt, ossl_rsa_public_decrypt, ossl_rsa_private_encrypt, ossl_rsa_private_decrypt): Ditto. RSA_size() does not check rsa->n.
