CVE-2017-7482 (retired)

Priority
Description
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.
Ubuntu-Description
石磊 discovered that the RxRPC Kerberos 5 ticket handling code in the Linux
kernel did not properly verify metadata. A remote attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code.
Notes
