CVE-2016-3134

Status Candidate

Red Hat Security Advisory 2016-1847-01
Posted Sep 15, 2016
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2016-1847-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A security flaw was found in the Linux kernel in the mark_source_chains() function in "net/ipv4/netfilter/ip_tables.c". It is possible for a user-supplied "ipt_entry" structure to have a large "next_offset" field. This field is not bounds checked prior to writing to a counter value at the supplied offset.

Red Hat Security Advisory 2016-1875-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. The kernel-rt packages have been upgraded to the kernel-3.10.0-327.36.1 source tree, which provides a number of bug fixes over the previous version. Security Fix: A security flaw was found in the Linux kernel in the mark_source_chains() function in "net/ipv4/netfilter/ip_tables.c". It is possible for a user-supplied "ipt_entry" structure to have a large "next_offset" field. This field is not bounds checked prior to writing to a counter value at the supplied offset.
