CVE-2016-3707 medium priority: Ubuntu including 31 source packages (linux, linux-aws, …), 186 status rows across 6 suites (bionic, eoan, focal, trusty, upstream, xenial): DNE 95, not-affected 91.
The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel, as used in the kernel-rt package before 3.10.0-327.22.1 in Red Hat Enterprise Linux for Real Time 7 and other products, allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file.
