Arch Linux Security Advisory ASA-201612-11 ========================================== Severity: High Date : 2016-12-10 CVE-ID : CVE-2016-9919 Package : linux-grsec Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-103 Summary ======= The package linux-grsec before version 1:4.8.12.r201612062306-2 is vulnerable to denial of service. Resolution ========== Upgrade to 1:4.8.12.r201612062306-2. # pacman -Syu "linux-grsec>=1:4.8.12.r201612062306-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== The icmp6_send function in net/ipv6/icmp.c in the Linux kernel through 4.8.12 omits a certain check of the dst data structure, which allows remote attackers to cause a denial of service (panic) via a fragmented IPv6 packet. Impact ====== A remote attacker can cause a kernel panic by sending a fragmented IPv6 packet.
