GHSA-HX7C-3C6C-MHM3

Vulnerability from github – Published: 2022-05-13 01:28 – Updated: 2025-12-03 21:30

Details

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.

Severity ?

9.8 (Critical)


                  
                    CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
