If there are large number of BSSes in the scan results, BSS table update could have added a BSS entry to the last_scan_res in a case where that BSS entry got just deleted. This would happen only if there are more than bss_max_count (by default 200) BSSes and if at least bss_max_count of those BSSes are known (match a configured network). In such a case, wpa_bss_add() could end up allocating a new BSS entry and return a pointer to that entry even if it was the one that ended up getting freed to keep the BSS table length within the limit. This could result in freed memory being used and the process crashing (likely with segfault) when trying to access information from that BSS entry. Fix the issue by removing the oldest BSS entry before linking the new entry to the table. This makes sure the newly added entry will never get picked up as the one to be deleted immediately.

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2013, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These programs are licensed under the BSD license (the one with advertisement clause removed). If you are submitting changes to the project, please see CONTRIBUTIONS file for more instructions. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
