[security-announce] Upcoming update for shim requires confirmation on reboot
Hello,

we will release a security update for shim next week that fixes three
security issues, tracked in bnc#889332:
- OOB read access when parsing DHCPv6 packets (remote DoS) (CVE-2014-3675).
- Heap overflow when parsing IPv6 addresses provided by tftp:// DHCPv6 boot
option (RCE) (CVE-2014-3676).
- Memory corruption when processing user provided MOK lists (CVE-2014-3677).

Because of those issues we update shim to version 0.7.318.81ee561d. This
version includes a patch that requires the user to confirm a dialog once
on the first boot after the update is installed. You will need to be able
to confirm this dialog, which appears before the bootloader, or your system
will not boot. This only affects users that are still on openSUSE 13.1 and
use a secure boot setup. You can check with 'bootctl' if you're using a
secure boot configuration if you're not sure.

Best regards,
Johannes Segitz
