Red Hat Security Advisory 2012-1148-01

Posted Aug 8, 2012

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-1148-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: A NULL pointer dereference flaw was found in the nf_ct_frag6_reasm() function in the Linux kernel's netfilter IPv6 connection tracking implementation. A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the nf_conntrack_ipv6 kernel module loaded, causing it to crash.
