The remote Scientific Linux host is missing one or more security
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.
- 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.
The system must be rebooted for this update to take effect.
