Open vSwitch (aka openvswitch) 2.11.0 through 2.15.0 has a use-after-free in decode_NXAST_RAW_ENCAP (called from ofpact_decode and ofpacts_decode) during the decoding of a RAW_ENCAP action.

2.14 patch: https://github.com/openvswitch/ovs/commit/8ce8dc34b5f73b30ce0c1869af9947013c3c6575
2.15 patch: https://github.com/openvswitch/ovs/commit/38744b1bcb022c611712527f039722115300f58f

The vulnerability is fixed in the 2.15 branch with 2.15.1 and there seems to
be no release with 2.14's fix.
