Title: Compute node filesystem injection/corruption
Impact: Critical
Reporter: Pádraig Brady (Red Hat)
Products: Nova
Affects: All versions
Description:
Pádraig Brady from Red Hat discovered that the fix implemented for CVE-2012-3361 (OSSA-2012-008) was not covering all attack scenarios. By crafting a malicious image with root-readable-only symlinks and requesting a server based on it, an authenticated user could still corrupt arbitrary files (all setups affected) or inject arbitrary files (Essex and later setups with OpenStack API enabled and a libvirt-based hypervisor) on the host filesystem, potentially resulting in full compromise of that compute node.
