Impact
Unauthenticated adjacent attackers can execute code as root or crash the device by sending a malicious EAPOL frame. They only need access to a local network segment connected to an 802.1X-authenticated interface.
Root cause
A heap-based buffer overflow flaw in the secure-dot1xd process handling incoming EAPOL frames.

CVSS v3.1 · CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Fix & remediation
Upgrade Junos OS and Junos OS Evolved to the resolved releases referenced in JSA112187, or disable 802.1X authentication on exposed interfaces if patching must wait.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
