In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when
using the RXRPC keys incorrectly assumes the size of a field. This could
lead to the size-remaining variable wrapping and the data pointer going
over the end of the buffer. This could possibly lead to memory corruption
and possible privilege escalation.

Notes

Author Note
sbeattie RxRPC is used for AFS
