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(+) + +diff --git a/src/p2p/p2p.c b/src/p2p/p2p.c +index f584fae..a45fe73 100644 +--- a/src/p2p/p2p.c ++++ b/src/p2p/p2p.c +@@ -778,6 +778,7 @@ int p2p_add_device(struct p2p_data *p2p, const u8 *addr, int freq, + 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)) { +-- +1.9.1 + |
