Descriptions
The do_free_upto function in crypto/cms/cms_smime.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (infinite loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized X.660 OID for a hash function.
La función do_free_upto en crypto/cms/cms_smime.c en OpenSSL anterior a 0.9.8zg, 1.0.0 anterior a 1.0.0s, 1.0.1 anterior a 1.0.1n, y 1.0.2 anterior a 1.0.2b permite a atacantes remotos causar una denegación de servicio (bucle infinito) a través de vectores que provocan un valor nulo de una estructura de datos BIO, tal y como fue demostrado mediante un X.660 OID no reconocido para una función hash.
A denial of service flaw was found in the way OpenSSL verified certain signed messages using CMS (Cryptographic Message Syntax). A remote attacker could cause an application using OpenSSL to use excessive amounts of memory by sending a specially crafted message for verification.
