"We (the -stable team) are announcing the release of the 2.6.22.7 kernel. It contains a single security bugfix for the x86_64 architecture. There is potential for local privilege escalation, so all x86_64 users are certainly encouraged to upgrade.

CVE-2007-4573: x86_64: Zero extend all registers after ptrace in 32bit entry path.

I'll also be replying to this message with a copy of the patch between 2.6.22.6 and 2.6.22.7

The updated 2.6.22.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.22.y.git
and can be browsed at the normal kernel.org git web browser:

thanks,
