VMSA-2010-0018 : VMware hosted products and ESX patches resolve multiple security issues

high Nessus Plugin ID 50985

Language:

Synopsis

The remote VMware ESX host is missing a security-related patch.

Description

a. VMware Workstation, Player and Fusion vmware-mount race condition

 The way temporary files are handled by the mounting process could result in a race condition. This issue could allow a local user on the host to elevate their privileges.

 VMware Workstation and Player running on Microsoft Windows are not affected.

 The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4295 to this issue.

 VMware would like to thank Dan Rosenberg for reporting this issue.

b. VMware Workstation, Player and Fusion vmware-mount privilege escalation

 vmware-mount which is a suid binary has a flaw in the way libraries are loaded. This issue could allow local users on the host to execute arbitrary shared object files with root privileges.

 VMware Workstation and Player running on Microsoft Windows are not affected.

 The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4296 to this issue.

 VMware would like to thank Martin Carpenter for reporting this issue.

c. OS Command Injection in VMware Tools update

 A vulnerability in the input validation of VMware Tools update allows for injection of commands. The issue could allow a user on the host to execute commands on the guest operating system with root privileges.

 The issue can only be exploited if VMware Tools is not fully up-to-date. Windows-based virtual machines are not affected.

 The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4297 to this issue.

 VMware would like to thank Nahuel Grisolia of Bonsai Information Security, http://www.bonsai-sec.com, for reporting this issue.

d. VMware VMnc Codec frame decompression remote code execution

 The VMware movie decoder contains the VMnc media codec that is required to play back movies recorded with VMware Workstation, VMware Player and VMware ACE, in any compatible media player. The movie decoder is installed as part of VMware Workstation, VMware Player and VMware ACE, or can be downloaded as a stand alone package.

 A function in the decoder frame decompression routine implicitly trusts a size value. An attacker can utilize this to miscalculate a destination pointer, leading to the corruption of a heap buffer, and could allow for execution of arbitrary code with the privileges of the user running an application utilizing the vulnerable codec.

 For an attack to be successful the user must be tricked into visiting a malicious web page or opening a malicious video file on a system that has the vulnerable version of the VMnc codec installed.

 The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4294 to this issue.

 VMware would like to thank Aaron Portnoy and Logan Brown of TippingPoint DVLabs for reporting this issue.
