Descriptions

The decrypt_public function in lib/crypt.cpp in the client in Berkeley Open Infrastructure for Network Computing (BOINC) 6.2.14 and 6.4.5 does not check the return value from the OpenSSL RSA_public_decrypt function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.

La función decrypt_public en lib/crypt.cpp en el cliente Berkeley Open Infrastructure for Network Computing (BOINC) v6.2.14 y v6.4.5, no comprueba adecuadamente el valor de retorno de la función OpenSSL RSA_public_decrypt, lo que permitiría a atacantes remotos evitar la validación en cadena de los certificados a través de una firma SSL/TLS malformada, una vulnerabilidad similar a CVE-2008-5077.
