-Subject: [PATCH] WPS: Fix HTTP chunked transfer encoding parser
-
-strtoul() return value may end up overflowing the int h->chunk_size and
-resulting in a negative value to be stored as the chunk_size. This could
-result in the following memcpy operation using a very large length
-argument which would result in a buffer overflow and segmentation fault.
-
-This could have been used to cause a denial service by any device that
-has been authorized for network access (either wireless or wired). This
-would affect both the WPS UPnP functionality in a WPS AP (hostapd with
-upnp_iface parameter set in the configuration) and WPS ER
-(wpa_supplicant with WPS_ER_START control interface command used).
-
-Validate the parsed chunk length value to avoid this. In addition to
-rejecting negative values, we can also reject chunk size that would be
-larger than the maximum configured body length.
-
-Thanks to Kostya Kortchinsky of Google security team for discovering and
-reporting this issue.

-Subject: [PATCH] AP WMM: Fix integer underflow in WMM Action frame parser
-
-The length of the WMM Action frame was not properly validated and the
-length of the information elements (int left) could end up being
-negative. This would result in reading significantly past the stack
-buffer while parsing the IEs in ieee802_11_parse_elems() and while doing
-so, resulting in segmentation fault.
-
-This can result in an invalid frame being used for a denial of service
-attack (hostapd process killed) against an AP with a driver that uses
-hostapd for management frame processing (e.g., all mac80211-based
-drivers).
-
-Thanks to Kostya Kortchinsky of Google security team for discovering and
-reporting this issue.
