Descriptions
MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly expects that a krb5_read_message data field is represented as a string ending with a '\0' character, which allows remote attackers to (1) cause a denial of service (NULL pointer dereference) via a zero-byte version string or (2) cause a denial of service (out-of-bounds read) by omitting the '\0' character, related to appl/user_user/server.c and lib/krb5/krb/recvauth.c.
MIT Kerberos 5 (también conocido como krb5) hasta 1.13.1 espera incorrectamente que un campo de datos krb5_read_message se representa como una cadena que termine con un caracter '\0', lo que permite a atacantes remotos (1) causar una denegación de servicio (referencia a puntero nulo) a través de una cadena de versión de cero bytes o (2) causar una denegación de servicio (lectura fuera de rango) mediante la omisión del caracter '\0', relacionado con appl/user_user/server.c y lib/krb5/krb/recvauth.c.
It was found that the krb5_read_message() function of MIT Kerberos did not correctly sanitize input, and could create invalid krb5_data objects. A remote, unauthenticated attacker could use this flaw to crash a Kerberos child process via a specially crafted request.
