Fixes the following security issue:
- wpa_supplicant P2P group information processing vulnerability (no CVE yet)
A vulnerability was discovered in how wpa_supplicant processing P2P
(Wi-Fi Direct) group information from active group owners. The actual
parsing of that information validates field lengths appropriately, but
processing of the parsed information misses a length check when storing a
copy of the secondary device types. This can result in writing attacker
controlled data into the peer entry after the area assigned for the
secondary device type. The overflow can result in corrupting pointers
for heap allocations. This can result in an attacker within radio range
of the device running P2P discovery being able to cause unexpected
behavior, including termination of the wpa_supplicant process and
potentially arbitrary code execution.
