Synopsis: Important: kernel security update
Issue Date: 2013-03-11
CVE Numbers: CVE-2013-0871
CVE-2013-0268
—
This update fixes the following security issues:
* A flaw was found in the way file permission checks for the
“/dev/cpu/[x]/msr” 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)
The system must be rebooted for this update to take effect.
