CVE-2005-1174

CVE-2005-1174 affects MIT Kerberos 5 (krb5) KDC; a remote attacker can crash the KDC by sending a certain TCP connection that frees memory twice (heap corruption). The related issues include CVE-2005-1175 (potential remote code execution via a rare TCP request triggering a buffer overflow) and CV...
