CVE-2014-5355

CVE Details

Release Date:

2014-12-09

Description

MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly expects that akrb5_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.
