-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------- VMware Security Advisory Advisory ID: VMSA-2006-0003 Synopsis: VMware possible incorrect permissions on SSL key files VMware Player for Linux VMware Workstation for Linux VMware Server for Linux VMware ESX Server 2.x VMware Infrastructure 3 NOT VULNERABLE: VMware Player for Windows NOT VULNERABLE: VMware Workstation for Windows NOT VULNERABLE: VMware Server for Windows VMTN Knowledge Base URL: http://kb.vmware.com/kb/2467205 Issue date: 2006-07-18 Updated on: 2006-07-18 CVE Name: CVE-2006-3589 - ------------------------------------------------------------------- 1. Summary: The configuration program, vmware­config.pl, may not correctly set file permissions on the generated SSL Key files which is used for encrypting traffic for remote administrative connections. VMware has given this issue a Priority 3 severity rating. 2. Relevant release: VMware Player for Linux VMware Workstation for Linux VMware Server for Linux VMware Infrastructure 3 NOT VULNERABLE: VMware Player for Windows NOT VULNERABLE: VMware Workstation for Windows NOT VULNERABLE: VMware Server for Windows 3. Problem description: The script vmware-config.pl sets permissions on the key and certificate files to safe values. However this script does not use the safe_chmod() subroutine which reports errors on failure. Instead, the native Perl chmod() function is used, without any return code checking. Because the safe_chmod() subroutine is not used and no return code checks are performed, the user is not alerted if the chmod() fails. Depending on the umask being used at the time this could leave the key file readable to any local user on the system. 4. Solution: VMware is working on a fix, and there is a workaround. Manually change the permissions on the key and certificate to its intended values. The following commands would be appropriate on a default installation: # chmod 400 /etc/vmware/ssl/rui.key # chmod 444 /etc/vmware/ssl/rui.crt The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2006-3589 to this issue. 5.
