CVE-2014-3519: The open_by_handle_at function in vzkernel before 042stab090.5 in the OpenVZ modification for the Linux ker...

Security readout for executives and security teams

This is a legacy OpenVZ container-isolation flaw. Under specific conditions, a user inside a container could bypass intended file-access boundaries and read arbitrary files on the underlying filesystem. The business risk is strongest for multi-tenant or hosted environments where container isolation is a security boundary. Exposure appears limited to legacy OpenVZ or Virtuozzo-style deployments using affected vzkernel builds, simfs, and containers granted CAP_DAC_READ_SEARCH. The provided affected-product metadata is incomplete, so inventory should focus on kernel build and storage configuration rather than product name alone. Prioritize this where legacy OpenVZ hosts support customer, partner, or untrusted workloads. The issue directly affects container isolation, but the evidence points to specific old configurations rather than broad modern Linux exposure. Mitigation focus: Update affected OpenVZ vzkernel systems to 042stab090.5 or later vendor guidance.; Apply relevant Virtuozzo or Parallels core updates referenced by the vendor advisories.; Remove CAP_DAC_READ_SEARCH from containers unless explicitly required..
