+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).

+
+The length of the received Commit and Confirm message payloads was not

+fixes an issue where these flags from the server could have been invalid

+Subject: [PATCH] NFC: Fix payload length validation in NDEF record parser
+
+It was possible for the 32-bit record->total_length value to end up
+wrapping around due to integer overflow if the longer form of payload
+length field is used and record->payload_length gets a value close to
+2^32. This could result in ndef_parse_record() accepting a too large
+payload length value and the record type filter reading up to about 20
+bytes beyond the end of the buffer and potentially killing the process.
+This could also result in an attempt to allocate close to 2^32 bytes of
+heap memory and if that were to succeed, a buffer read overflow of the
+same length which would most likely result in the process termination.
+In case of record->total_length ending up getting the value 0, there
+would be no buffer read overflow, but record parsing would result in an
+infinite loop in ndef_parse_records().
+
+Any of these error cases could potentially be used for denial of service
+attacks over NFC by using a malformed NDEF record on an NFC Tag or
+sending them during NFC connection handover if the application providing
+the NDEF message to hostapd/wpa_supplicant did no validation of the
+received records. While such validation is likely done in the NFC stack
+that needs to parse the NFC messages before further processing,
+hostapd/wpa_supplicant better be prepared for any data being included
+here.
+
+Fix this by validating record->payload_length value in a way that
+detects integer overflow. (CID 122668)

+
+    Select AP based on estimated maximum throughput
+    
+    This modifies the BSS selection routines to calculate SNR and estimated
+    throughput for each scan result and then use the estimated throughput as
+    a criteria for sorting the results. This extends the earlier design by
+    taking into account higher throughput rates if both the AP and local
+    device supports HT20, HT40, or VHT80. In addition, the maximum rate is
+    restricted based on SNR.
+    
+    In practice, this gives significantly higher probability of selecting
+    HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
+    low enough to prevent higher MCS use.

+Author: Mukesh Agrawal <quiche at chromium.org>
+Date:   Tue Apr 8 17:54:49 2014 -0700
+
+    Improve BSS selection with default noise floor values
+    
+    When noise floor measurements are not available, compute SNR
+    using default values for the noise floor. This helps steer us
+    towards 5 GHz BSSes in high signal strength environments.
+    
+    In more detail...
+    
+    Existing code prefers a 5 GHz BSS when the 5 GHz BSS's signal
+    strength is "close" to that of the 2.4 GHz BSS, or when both SNRs
+    are large. However, the mwifiex driver does not provide noise
+    floor measurements, so we can't compute SNRs.
+    
+    Because mwifiex doesn't provide NF measurements, the "large SNR"
+    code wasn't effective. By using default values for the noise floor,
+    we can again compute SNRs, and decide that the SNR is high enough
+    that we shouldn't worry about the exact difference in SNR.
+    
+    The default noise floor values (one for 2.4 GHz, and one for 5 GHz)
+    were chosen by measurement in a noisy environment, so they should be
+    conservative.
+    
+    Note that while this patch is motivated by mwifiex, it affects
+    ath9k as well. Although ath9k provides noise floor measurements
+    in general, it will sometimes fail to provide a measurement for
+    one or more specific channels.
+    
+    As a result of this patch, we'll always compare BSSes based on SNR
+    (either measured or estimated), rather than sometimes comparing
+    based on signal strength. ("Always" assumes that the
+    WPA_SCAN_LEVEL_DBM flag is set. It is for mwifiex and ath9k.)
+    
+    While there:
+    - fix a whitespace issue (spaces -> tab)
