| Description | The code in pppd that formats a response to a PEAP Request packet in peap_response() copies an entire TLS record of up to 16384 bytes into the fixed global buffer outpacket_buf without checking the available space and without implementing outgoing PEAP fragmentation. Thus a pppd process connecting to a server which requests PEAP authentication can be induced to corrupt global static data following the outpacket_buf array, most likely causing incorrect behavior or a crash. | A flaw was found in pppd. A remote attacker could exploit a buffer overflow vulnerability in the PEAP response handling. By sending a specially crafted PEAP Request packet, an attacker could cause the pppd process to corrupt global static data, leading to incorrect behavior or a system crash. |
