The length provided by the peer device (0..255 bytes) -was used without proper bounds checking and that could have resulted in -arbitrary data of up to 223 bytes being written beyond the end of the -dev->oper_ssid[] array (of which about 150 bytes would be beyond the -heap allocation) when processing a corrupted management frame for P2P -peer discovery purposes. - -This could result in corrupted state in heap, unexpected program -behavior due to corrupted P2P peer device information, denial of service -due to process crash, exposure of memory contents during GO Negotiation, -and potentially arbitrary code execution. - -Thanks to Google security team for reporting this issue and smart -hardware research group of Alibaba security team for discovering it. - -Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> ---- - src/p2p/p2p.c | 1 + - 1 file changed, 1 insertion(+) - ---- a/src/p2p/p2p.c -+++ b/src/p2p/p2p.c -@@ -778,6 +778,7 @@ int p2p_add_device(struct p2p_data *p2p, - if (os_memcmp(addr, p2p_dev_addr, ETH_ALEN) != 0) - os_memcpy(dev->interface_addr, addr, ETH_ALEN); - if (msg.ssid && -+ msg.ssid[1] <= sizeof(dev->oper_ssid) && - (msg.ssid[1] != P2P_WILDCARD_SSID_LEN || - os_memcmp(msg.ssid + 2, P2P_WILDCARD_SSID, P2P_WILDCARD_SSID_LEN) - != 0)) { |
