shim: out-of-bounds memory read flaw in DHCPv6 packet processing
Shim allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted DHCPv6 packet.
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.
No detection rules found.

CVE-2014-3675 shim: out-of-bounds memory read flaw in DHCPv6 packet processing
An out-of-bounds memory read flaw was found in shim when IPv6 network booting was enabled. A specially-crafted DHCPv6 packet could possibly cause shim to crash, preventing the system from booting.
Note that performing a secure boot over the network is not a common scenario.
