Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> rxrpc: Fix re-decryption of RESPONSE packets<br /> <br /> If a RESPONSE packet gets a temporary failure during processing, it may end<br /> up in a partially decrypted state - and then get requeued for a retry.<br /> <br /> Fix this by just discarding the packet; we will send another CHALLENGE<br /> packet and thereby elicit a further response. Similarly, discard an<br /> incoming CHALLENGE packet if we get an error whilst generating a RESPONSE;<br /> the server will send another CHALLENGE.
