sshing to a compromised machine with X forwarding enabled is already a
big enough problem without adding root exploits.

Don't ssh with X forwarding to an untrusted machine. Ever. X is not a
secure protocol and with access to your X server a program can wreak
havoc on anything you do on that X server including capturing passwords
and other sensitive data. It's not an issue specific to this vulnerability.
