Improper input validation together with an integer overflow in the EAP-TLS
protocol implementation in PPPD may cause a crash, information disclosure,
or authentication bypass. This implementation is distributed as a patch for
PPPD 0.91, and includes the affected eap.c and eap-tls.c files.
Configurations that use the refuse-app option are unaffected.
