pygrub (tools/pygrub/src/GrubConf.py) in Xen 3.0.3, when booting a guest domain, allows local users with elevated privileges in the guest domain to execute arbitrary commands in domain 0 via a crafted grub.conf file whose contents are used in exec statements.

Security readout for executives and security teams

CVE-2007-4993 is a Xen pygrub flaw where a privileged user inside a guest VM could influence boot configuration so commands run in domain 0, the host control domain. That creates a serious guest-to-host boundary risk for old Xen 3.0.3 deployments. Exposure is most likely in legacy Xen 3.0.3 systems or vendor-packaged Xen builds referenced by 2007 advisories. The provided affected-product metadata is incomplete, so validate through package inventory and vendor advisory mapping. Prioritize if any legacy Xen 3.0.3 infrastructure remains, especially multi-tenant or externally administered guest environments. Modern environments are likely unaffected, but stale virtualization hosts carry high business risk because compromise crosses from guest to host control domain. Mitigation focus: Identify any Xen 3.0.3 or related vendor Xen packages in use.; Apply the relevant vendor Xen updates from the cited advisories.; Avoid booting untrusted guest images with pygrub until remediated..
