The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not validate that a message is long enough to contain the Total-Length field, which allows remote attackers to cause a denial of service (crash) via a crafted message.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
