-
The tcpmssmanglepacket function in net/netfilter/xtTCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xtTCPMSS in an iptables action.
