CVE-2013-3230: The l2tp_ip6_recvmsg function in net/l2tp/l2tp_ip6.c in the Linux kernel before 3.9-rc7 does not initialize...

Security readout for executives and security teams

This is an old Linux kernel information disclosure flaw. A local user could cause the kernel to return data left in stack memory through the L2TP over IPv6 receive path. It is not described as remote code execution, but leaked kernel memory can expose sensitive data or help chain other attacks. Exposure is limited to systems running vulnerable Linux kernels before 3.9-rc7 or downstream vendor kernels before their 2013 updates. Multi-user Linux servers, shared hosting, legacy appliances, and container hosts using an old shared kernel are the most relevant cases. Treat as a legacy exposure cleanup item unless vulnerable kernels still support shared or multi-user workloads. It should not outrank actively exploited remote flaws, but unsupported old kernels create compounding operational risk. Mitigation focus: Upgrade affected Linux kernels using vendor security updates.; Confirm Fedora, Ubuntu, or openSUSE systems received their 2013 kernel advisory fixes.; For unsupported systems, migrate to a maintained kernel or vendor-supported platform..
