Description Mark J. Cox 2005-06-09 09:29:01 UTC

The following upstream patch checks if ptrace RIP is canonical; without this a
user can cause a crash.

Mark, this bug and bug 159917 are mixed up.  You reversed the CVE names.

Changing this summary to "CAN-2005-0756 x86_64 crash (ptrace-canonical)".
