The remote Scientific Linux host is missing one or more security
This update fixes the following security issues :
- It was found that a deadlock could occur in the Out of
Memory (OOM) killer. A process could trigger this
deadlock by consuming a large amount of memory, and then
causing request_module() to be called. A local,
unprivileged user could use this flaw to cause a denial
of service (excessive memory consumption).
- A flaw was found in the way the KVM (Kernel-based
Virtual Machine) subsystem handled guests attempting to
run with the X86_CR4_OSXSAVE CPU feature flag set. On
hosts without the XSAVE CPU feature, a local,
unprivileged user could use this flaw to crash the host
system. (The 'grep --color xsave /proc/cpuinfo' command
can be used to verify if your system has the XSAVE CPU
feature.) (CVE-2012-4461, Moderate)
- A memory disclosure flaw was found in the way the
load_script() function in the binfmt_script binary
format handler handled excessive recursions. A local,
unprivileged user could use this flaw to leak kernel
stack memory to user-space by executing
specially-crafted scripts. (CVE-2012-4530, Low)
The system must be rebooted for this update to take effect.
