This update fixes the following security issues:
* 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.
* A flaw was found in the way the Linux kernel's key management facility
handled replacement session keyrings on process forks. A local,
unprivileged user could use this flaw to cause a denial of service.
