- -------------------------------------------------------------------
1. Summary:
~ Several critical security vulnerabilities have been addressed
~ in the newest releases of VMware's hosted product line.
2. Relevant releases:
~ VMware Workstation 6.0.2 and earlier
~ VMware Workstation 5.5.4 and earlier
~ VMware Player 2.0.2 and earlier
~ VMware Player 1.0.4 and earlier
~ VMware ACE 2.0.2 and earlier
~ VMware ACE 1.0.2 and earlier
~ VMware Server 1.0.4 and earlier
~ VMware Fusion 1.1 and earlier
3. Problem description:
~ a. Host to guest shared folder (HGFS) traversal vulnerability
~ On Windows hosts, if you have configured a VMware host to guest
~ shared folder (HGFS), it is possible for a program running in the
~ guest to gain access to the host's file system and create or modify
~ executable files in sensitive locations.
NOTE: VMware Server is not affected because it doesn't use host to
~ guest shared folders. No versions of ESX Server, including
~ ESX Server 3i, are affected by this vulnerability. Because
~ ESX Server is based on a bare-metal hypervisor architecture
~ and not a hosted architecture, and it doesn't include any
~ shared folder abilities. Fusion and Linux based hosted
~ products are unaffected.
~ VMware would like to thank CORE Security Technologies for
~ working with us on this issue. This addresses advisory
~ CORE-2007-0930.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org)
~ has assigned the name CVE-2008-0923 to this issue.
~ Hosted products
~ ---------------
~ VMware Workstation 6.0 upgrade to version 6.0.3 (Build# 80004)
~ VMware Workstation 5.5 upgrade to version 5.5.6 (Build# 80404)
~ VMware Player 2.0 upgrade to version 2.0.3 (Build# 80004)
~ VMware Player 1.0 upgrade to version 1.0.6 (Build# 80404)
~ VMware ACE 2.0 upgrade to version 2.0.1 (Build# 80004)
~ VMware ACE 1.0 upgrade to version 1.0.5 (Build# 79846)
~ b. Insecure named pipes
~ An internal security audit determined that a malicious Windows
~ user could attain and exploit LocalSystem privileges by causing
~ the authd process to connect to a named pipe that is opened and
~ controlled by the malicious user.
~ The same internal security audit determined that a malicious
~ Windows user could exploit an insecurely created named pipe
~ object to escalate privileges or create a denial of service
~ attack. In this situation, the malicious user could
~ successfully impersonate authd and attain privileges under
~ which Authd is executing.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org)
~ has assigned the names CVE-2008-1361, CVE-2008-1362 to these
~ issues.
~ Windows Hosted products
~ ---------------
~ VMware Workstation 6.0 upgrade to version 6.0.3 (Build# 80004)
~ VMware Workstation 5.5 upgrade to version 5.5.6 (Build# 80404)

~ c. Updated libpng library to version 1.2.22 to address various
~ security vulnerabilities
~ Several flaws were discovered in the way libpng handled various PNG
~ image chunks. An attacker could create a carefully crafted PNG
~ image file in such a way that it could cause an application linked
~ with libpng to crash when the file was manipulated.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org)
~ has assigned the name CVE-2007-5269 to this issue.
~ Hosted products

~ NOTE: Fusion is not affected by this issue.
~ d. Updated OpenSSL library to address various security vulnerabilities
~ Updated OpenSSL fixes several security flaws were discovered
~ in previous versions of OpenSSL.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org)
~ assigned the following names to these issues: CVE-2006-2940,
~ CVE-2006-2937, CVE-2006-4343, CVE-2006-4339.
~ Hosted products

~ VMware ACE 2.0 upgrade to version 2.0.1 (Build# 80004)
~ VMware ACE 1.0 upgrade to version 1.0.5 (Build# 79846)
~ NOTE: Fusion is not affected by this issue.
~ e. VIX API default setting changed to a more secure default value
~ Workstation 6.0.2 allowed anonymous console access to the guest by
~ means of the VIX API. This release, Workstation 6.0.3, disables
~ this feature. This means that the Eclipse Integrated Virtual
~ Debugger and the Visual Studio Integrated Virtual Debugger will now
~ prompt for user account credentials to access a guest.

~ it may be possible to crash the host system by making specially
~ crafted calls to the VMCI interface. This may result in denial
~ of service via memory exhaustion and memory corruption.
