Descriptions

Multiple integer underflows in the (1) AES and (2) RC4 decryption functionality in the crypto library in MIT Kerberos 5 (aka krb5) 1.3 through 1.6.3, and 1.7 before 1.7.1, allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid.

Múltiples vulnerabilidades de desbordamiento de entero en la funcionalidad de desencriptado AES y RC4 en la biblioteca crypto en MIT Kerberos 5 (también conocido comokrb5) v1.3 a la v1.6.3, y 1.7 anterior a v1.7.1, permite a atacantes remotos provocar una denegación de servición (caída de demonio) o posiblemente la ejecución de código de su elección facilitando texto cifrado (ciphertext) con un tamaño menor al válido.
