Description

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.

Affected configurations

• linux linux kernel (<= 4.5.5) • oracle linux 7 • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • canonical ubuntu linux 15.10 • canonical ubuntu linux 16.04
