+Subject: [PATCH] pcnet: force the buffer access to be in bounds during tx
+
+4096 is the maximum length per TMD and it is also currently the size of
+the relay buffer pcnet driver uses for sending the packet data to QEMU
+for further processing. With packet spanning multiple TMDs it can
+happen that the overall packet size will be bigger than sizeof(buffer),
+which results in memory corruption.
+
+Fix this by only allowing to queue maximum sizeof(buffer) bytes.
+
+This is CVE-2015-3209.
+
+[Fixed 3-space indentation to QEMU's 4-space coding standard.

+ buffer
+
+During processing of certain commands such as FD_CMD_READ_ID and
+FD_CMD_DRIVE_SPECIFICATION_COMMAND the fifo memory access could
+get out of bounds leading to memory corruption with values coming
+from the guest.
+
+Fix this by making sure that the index is always bounded by the

+Optimize STMT_SELECT_EXTERNALS_DEFINED when using Sqlite 3.8.9, by
+adding two more rows to the sqlite_stat1 table.
+
+This fixes a test failure in wc-queries-test.c, but actual users most
+likely don't notice a difference as a tablescan on an EXTERNALS tables
+index is not that expensive, given that most working copies don't have
+many externals.
+
+* subversion/libsvn_wc/wc-metadata.sql
+  (STMT_INSTALL_SCHEMA_STATISTICS): Add two rows.
+
+* subversion/tests/libsvn_wc/wc-queries-test.c
+  (test_schema_statistics): Add a dummy externals row to allow
+    verifying schema.

+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).

+Subject: [PATCH 5/5] EAP-pwd peer: Fix asymmetric fragmentation behavior
+
+The L (Length) and M (More) flags needs to be cleared before deciding
+whether the locally generated response requires fragmentation. This
+fixes an issue where these flags from the server could have been invalid
+for the following message. In some cases, this could have resulted in
+triggering the wpabuf security check that would terminate the process
+due to invalid buffer allocation.
