Summary
krb5 vulnerability
Details

Robert Morris discovered that Kerberos did not properly handle memory access when processing RPC data through kadmind, which could lead to the freeing of uninitialized memory. An authenticated remote attacker could possibly use this issue to cause kadmind to crash, resulting in a denial of service.
