Security readout for executives and security teams

This is a Linux kernel information leak. A local user on an affected kernel could cause the system to expose data from kernel stack memory. It is not described as remote code execution, but leaked kernel memory can reduce defenses and support later attacks. Exposure is most relevant to systems running Linux kernels before 3.4.16 or vendor kernels that had not backported the fix. The sources name Ubuntu and Fedora advisories and a Red Hat bug, but the provided affected-product metadata is incomplete. Treat as a legacy Linux hygiene issue with moderate urgency. Patch affected kernels during normal security maintenance, faster on multi-user or shared-hosting systems where local users are less trusted. Mitigation focus: Upgrade to a vendor kernel containing the CVE-2012-0957 fix.; Check Ubuntu, Fedora, Red Hat, or your distribution advisory for backported packages.; Prioritize shared servers where untrusted local users can run code..
