Summary

A Heap-based Buffer Overflow vulnerability in the secure-dot1xd process of Juniper Networks on Junos OS and Junos OS Evolved allows an unauthenticated adjacent network attacker to execute code as root or cause a denial of service via an EAPOL frame sent to an 802.1X-authenticated interface.

Risk Assessment

An unauthenticated adjacent network attacker can remotely execute code with root privileges or cause a denial of service, posing a serious threat to device security.

Recommendation

Immediately upgrade Junos OS / Junos OS Evolved to a fixed release and consider disabling 802.1X on interfaces that do not require this authentication.
