Descriptions
Double free vulnerability in the dsa_priv_decode function in crypto/dsa/dsa_ameth.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a malformed DSA private key.
Vulnerabilidad de liberación doble en la función dsa_priv_decode en crypto/dsa/dsa_ameth.c en OpenSSL 1.0.1 en versiones anteriores a 1.0.1s y 1.0.2 en versiones anteriores a 1.0.2g permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto no especificado a través de una clave DSA privada malformada.
A double-free flaw was found in the way OpenSSL parsed certain malformed DSA (Digital Signature Algorithm) private keys. An attacker could create specially crafted DSA private keys that, when processed by an application compiled against OpenSSL, could cause the application to crash.
An update that contains security fixes can now be installed. This update for openssl fixes various security issues. OpenSSL was vulnerable to a cross-protocol attack that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. This update changes the openssl library to. Disable SSLv2 protocol support by default. This can be overridden by setting the environment variable "OPENSSL_ALLOW_SSL2" or by using SSL_CTX_clear_options using the SSL_OP_NO_SSLv2 flag. Note that various services and clients had already disabled SSL protocol 2 by default previously. Disable all weak EXPORT ciphers by default. These can be reenabled if required by old legacy software using the environment variable "OPENSSL_ALLOW_EXPORT".
