Title:	RHSA-2014:1801 -- shim security update (Moderate)
Description:	Shim is the initial UEFI bootloader that handles chaining to a trusted full bootloader under secure boot environments. A heap-based buffer overflow flaw was found the way shim parsed certain IPv6 addresses. If IPv6 network booting was enabled, a malicious server could supply a crafted IPv6 address that would cause shim to crash or, potentially, execute arbitrary code. (CVE-2014-3676) An out-of-bounds memory write flaw was found in the way shim processed certain Machine Owner Keys (MOKs). A local attacker could potentially use this flaw to execute arbitrary code on the system. (CVE-2014-3677) An out-of-bounds memory read flaw was found in the way shim parsed certain IPv6 packets. A specially crafted DHCPv6 packet could possibly cause shim to crash, preventing the system from booting if IPv6 booting was enabled. (CVE-2014-3675) Red Hat would like to thank the SUSE Security Team for reporting these issues. All shim users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
