b7c61c9d4e Fix validation of EAPOL-Key length with AES key wrap (CID 62859)
The additional eight octet field was removed from keydatalen without
proper validation of the Key Data Length field. It would have been
possible for an invalid EAPOL-Key frame to be processed in a way that
ends up reading beyond the buffer. In theory, this could have also
resulted in writing beyond the EAPOL-Key frame buffer, but that is
unlikely to be feasible due to the AES key wrap validation step on
arbitrary memory contents.

Commit b125c48fce ('P2P: Add wfd_dev_info=
field for device found event') added Wi-Fi Display device info to the
P2P-DEVICE-FOUND events. However, it did not include proper bounds
checking in wifi_display_subelem_hex() and could accept subelements with
invalid length field values. This could result in buffer read overflow
of up to 64 kB and inclusion of heap memory in the local control
interface event and/or process crash due to invalid memory access. Fix
this by checking the validity of the length field before writing a
hexdump of the data.

1851e17a64 dbus: Clean up P2P group vendor ext getter
The vendor_ext[i] = NULL setting did not make any sense since
num_vendor_ext should have been used to index the vendor_ext array. The
old code did not do any harm since i >= num_vendor_ext and none of the
already set entries could have been cleared. Anyway, better clean this
by making it skip the setting to NULL similarly to what was already done
in the P2P peer vendor ext getter.

062833c67c GAS server: Fix request frame length validation (CID 68098)
There seemed to be an off-by-one error in the validation of GAS request
frames. If a Public Action frame without the Action code field would
have reached this function, the length could have been passed as
(size_t) -1 which would likely have resulted in a crash due to reading
beyond the buffer. However, it looks like such frame would not be
delivered to hostapd at least with mac80211-based drivers. Anyway, this
function better be more careful with length validation should some other
driver end up reporting invalid Action frames.

In addition, the Action code field is in a fixed location, so the
IEEE80211_HDRLEN can be used here to clean up bounds checking to avoid
false reports from static analyzer.
