shim: heap-based buffer overflow flaw in IPv6 address parsing

CVE-2014-3676 [HIGH] CWE-122 shim: heap-based buffer overflow flaw in IPv6 address parsing
shim: heap-based buffer overflow flaw in IPv6 address parsing
Heap-based buffer overflow in Shim allows remote attackers to execute arbitrary code via a crafted IPv6 address, related to the "tftp:// DHCPv6 boot option."
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 shim: heap-based buffer overflow flaw in IPv6 address parsing
A heap-based buffer overflow flaw was found in shim when parsing IPv6 addresses. If IPv6 network booting were enabled, a malicious server could supply a crafted IPv6 address that would cause shim to crash or, potentially, execute arbitrary code.
Note that performing a secure boot over the network is not a common scenario.
