Description GLSAMaker/CVETool Bot gentoo-dev 2015-06-21 13:49:29 UTC 
CVE-2014-9715 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-9715):
  include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in
  the Linux kernel before 3.14.5 uses an insufficiently large data type for
  certain extension data, which allows local users to cause a denial of
  service (NULL pointer dereference and OOPS) via outbound network traffic
  that triggers extension loading, as demonstrated by configuring a PPTP
  tunnel in a NAT environment.
