Descriptions

libcrypt-openssl-dsa-perl does not properly check the return value from the OpenSSL DSA_verify and DSA_do_verify functions, which might allow remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.

libcrypt-openssl-dsa-perl no comprueba adecuadamente el valor de retorno de las funciones OpenSSL_DSA_verify y DSA_do_verify, lo que permitiria a atacantes remotos evitar la validacion de la cadena de certificados a traves de una firma SSL/TLS malformada, similar a la vulnerabilidad CVE-2008-5077.
