It’s kernel update time. This is the single security bug fix edition:
We (the -stable team) are announcing the release of the 18.104.22.168 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 22.214.171.124 and 126.96.36.199.
I’m going to go out on a limb and guess this won’t be the last we hear from lwn.net.
