VMSA-2008-0018 : VMware Hosted products and patches for ESX and ESXi resolve two security issues
High Nessus Plugin ID 40385
SynopsisThe remote VMware ESXi / ESX host is missing a security-related patch.
Descriptiona. A privilege escalation on 32-bit and 64-bit guest operating systems
VMware products emulate hardware functions and create the possibility to run guest operating systems.
A flaw in the CPU hardware emulation might allow the virtual CPU to incorrectly handle the Trap flag. Exploitation of this flaw might lead to a privilege escalation on guest operating systems. An attacker needs a user account on the guest operating system and have the ability to run applications.
VMware would like to thank Derek Soeder for discovering this issue and working with us on its remediation.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4915 to this issue.
b. Directory traversal vulnerability
VirtualCenter allows administrators to have fine-grained privileges.
A directory traversal vulnerability might allow administrators to increase these privileges. In order to leverage this flaw, the administrator would need to have the Datastore.FileManagement privilege.
VMware would like to thank Michel Toussaint for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4281 to this issue.
