Zusammenfassung:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Beschreibung:	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. This update fixes the following security issues: * A flaw was found in the way file permission checks for the files were performed in restricted root environments (for example, when using a capability-based security model). A local user with the ability to write to these files could use this flaw to escalate their privileges to kernel level, for example, by writing to the SYSENTER_EIP_MSR register. (CVE-2013-0268, Important) * A race condition was found in the way the Linux kernel's ptrace implementation handled PTRACE_SETREGS requests when the debuggee was woken due to a SIGKILL signal instead of being stopped. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2013-0871, Important) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. Affected Software/OS: kernel on CentOS 5 Solution: Please install the updated packages. CVSS Score: 6.9 CVSS Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C
