Description

The GSS-RPC layer in MIT Kerberos 5 (aka krb5) does not enforce size limits on XDR-decoded data, which allows remote authenticated users to cause a denial of service (memory exhaustion or excessive CPU consumption in kadmind) via crafted RPC requests that trigger unbounded memory allocations during XDR decoding.
