a. VMware ROM Overwrite Privilege Escalation A flaw in the way port-based I/O is handled allows for modifying Read-Only Memory that belongs to the Virtual DOS Machine.
Exploitation of this issue may lead to privilege escalation on Guest Operating Systems that run Windows 2000, Windows XP 32-bit, Windows Server 2003 32-bit or Windows Server 2003 R2 32-bit.
VMware would like to thank Derek Soeder of Ridgeway Internet Security, L.L.C. for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1515 to this issue.
b. ESX third-party update for Service Console kernel The ESX Service Console Operating System (COS) kernel is updated to kernel-400.2.6.18-238.4.11.591731 to fix multiple security issues in the COS kernel.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2011-2482, CVE-2011-3191 and CVE-2011-4348 to these issues.
c. ESX third-party update for Service Console krb5 RPM This patch updates the krb5-libs and krb5-workstation RPMs to version 1.6.1-63.el5_7 to resolve a security issue.
By default, the affected krb5-telnet and ekrb5-telnet services do not run. The krb5 telnet daemon is an xinetd service. You can run the following commands to check if krb5 telnetd is enabled :
/sbin/chkconfig --list krb5-telnet /sbin/chkconfig --list ekrb5-telnet The output of these commands displays if krb5 telnet is enabled.
You can run the following commands to disable krb5 telnet daemon :
/sbin/chkconfig krb5-telnet off /sbin/chkconfig ekrb5-telnet off The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-4862 to this issue.
