CVE-2016-1277 describes a denial-of-service vulnerability affecting Juniper Junos OS versions prior to specified updates across multiple release trains. This flaw allows remote attackers to trigger a kernel panic by sending a specially crafted ICMP packet to devices configured with GRE or IPIP tunnels. Rated as Medium severity (CVSS 5.9), the attack requires no user interaction and has high impact on availability, though with high attack complexity. There is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV entry, and community discussion and media coverage are minimal.
