Multiple vulnerabilities were identified in MIT Kerberos, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
The first issue occurs in the MIT krb5 Key Distribution Center (KDC) implementation when processing specially crafted TCP/UDP requests, which could be exploited by an unauthenticated attacker to cause a denial of service or execute arbitrary code on the KDC host.
The second vulnerability is due to a double-free error in the "krb5_recvauth()" function, which could be exploited by an unauthenticated remote attacker to execute arbitrary code in the context of a program calling the vulnerable function (this includes the kpropd program which typically runs on slave Key Distribution Center hosts).
