4 | Subject: [PATCH] P2P: Validate SSID element length before copying it | ||
5 | (CVE-2015-1863) | ||
6 | |||
7 | This fixes a possible memcpy overflow for P2P dev->oper_ssid in | ||
8 | p2p_add_device(). The length provided by the peer device (0..255 bytes) | ||
9 | was used without proper bounds checking and that could have resulted in | ||
10 | arbitrary data of up to 223 bytes being written beyond the end of the | ||
11 | dev->oper_ssid[] array (of which about 150 bytes would be beyond the | ||
12 | heap allocation) when processing a corrupted management frame for P2P | ||
13 | peer discovery purposes. | ||
14 | |||
15 | This could result in corrupted state in heap, unexpected program | ||
16 | behavior due to corrupted P2P peer device information, denial of service | ||
17 | due to process crash, exposure of memory contents during GO Negotiation, | ||
18 | and potentially arbitrary code execution. | ||
19 | |||
20 | Thanks to Google security team for reporting this issue and smart | ||
21 | hardware research group of Alibaba security team for discovering it. | ||
