CVE-2011-1006: Heap-based buffer overflow in the parse_cgroup_spec function in tools/tools-common.c in the Control Group C...

Security readout for executives and security teams

CVE-2011-1006 is an old libcgroup heap buffer overflow reachable by local command-line use of affected control-group tools. Sources say versions before 0.37.1 are affected and local users may gain privileges, but the CVE notes uncertainty about whether it crosses privilege boundaries. Treat it as legacy Linux exposure requiring inventory and patch confirmation. Most likely exposure is legacy Linux systems or embedded appliances still carrying libcgroup/libcg versions older than 0.37.1. Modern distributions are likely fixed, but long-lived servers, unsupported images, and vendor appliances should be checked. Medium operational priority for legacy environments; lower urgency for fully supported, patched Linux fleets. The main risk is local privilege escalation, not remote compromise, and the evidence does not confirm active exploitation. Mitigation focus: Upgrade libcgroup/libcg to 0.37.1 or a vendor-fixed package.; Prioritize unsupported or long-lived Linux hosts in the inventory.; Check Debian, Red Hat, Fedora, and openSUSE advisories for distro-specific packages..
