| Descripción: | Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.
Vulnerability 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.
