FPII-2340: Information disclosure vulnerability in kernel networking
subsystem (device specific) CVE-2016-4998 A-29637687
The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem,
in the Linux kernel before 4.6, allows local users to cause a denial of service (out-of-bounds read)
or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to
provide a crafted offset value that leads to crossing a ruleset blob boundary.
The fix is designed to add additional bounds checks to prevent the information disclosure vulnerability.
