Summary
The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory.
Insight
Insight
The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel's ptrace subsystem allowed a traced process's instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-4699, Important) Note: The CVE-2014-4699 issue only affected systems using an Intel CPU. * A flaw was found in the way the pppol2tp_setsockopt() and pppol2tp_getsockopt() functions in the Linux kernel's PPP over L2TP implementation handled requests with a non-SOL_PPPOL2TP socket option level. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-4943, Important) Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-4699, and Sasha Levin for reporting CVE-2014-4943. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
