If IPv6 network booting was enabled, a malicious server could supply a crafted IPv6 address thatwould 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) The system must be rebooted for this update to take effect. -- SL7 x86_64 mokutil-0.7-8.el7_0.x86_64.rpm shim-0.7-8.el7_0.x86_64.rpm shim-debuginfo-0.7-8.el7_0.x86_64.rpm shim-unsigned-0.7-8.el7_0.x86_64.rpm - Scientific Linux Development Team .
