CVE-2013-4588: Multiple stack-based buffer overflows in net/netfilter/ipvs/ip_vs_ctl.c in the Linux kernel before 2.6.33,...

Security readout for executives and security teams

This is a Linux kernel privilege-escalation issue in the IP Virtual Server feature. A local user or process with CAP_NET_ADMIN could trigger stack buffer overflows through IPVS socket controls. It matters most on legacy kernels before 2.6.33 with IPVS enabled. Exposure is likely limited to old Linux systems running kernels before 2.6.33 with CONFIG_IP_VS enabled. Systems also need a local user, service, or constrained environment where CAP_NET_ADMIN is available to an untrusted actor. Prioritize if legacy Linux systems still exist, especially shared hosts or systems granting network administration capabilities to workloads. Modern maintained distributions are less likely exposed, but unsupported kernels should be removed from production. Mitigation focus: Upgrade to a vendor kernel containing the upstream IPVS fix.; Review Ubuntu, Red Hat, or distribution-specific advisories for exact packages.; Disable IPVS support where it is not operationally required..
