Description GLSAMaker/CVETool Bot gentoo-dev 2017-05-18 06:07:19 UTC
CVE-2017-5972 (
  The TCP stack in the Linux kernel 3.x does not properly implement a SYN
  cookie protection mechanism for the case of a fast network connection, which
  allows remote attackers to cause a denial of service (CPU consumption) by
  sending many TCP SYN packets, as demonstrated by an attack against the
  kernel-3.10.0 package in CentOS Linux 7. NOTE: third parties have been
  unable to discern any relationship between the GitHub Engineering finding
  and the Trigemini.c attack code.
