Null pointer dereference

MIT Kerberos 5 aka krb5 through 1.13.1 incorrectly expects that a krb5readmessage 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...

CVE-2014-5355

Summary: CVE-2014-5355 affects MIT Kerberos 5 (krb5) where krb5_read_message() mis-handles input, causing a NULL pointer dereference with a zero-byte version string and an out-of-bounds read when the string is not null-terminated. Connected advisories indicate this was fixed in upstream krb5 (e.g...
