New VMware Security Advisory VMSA-2017-0009

Today VMware has released the following new security advisory:

VMSA-2017-0009 – VMware Workstation update addresses multiple security issues

This documents an important severity insecure library loading issue via ALSA sound driver configuration files (CVE-2017-4915) and a moderate severity NULL pointer dereference issue (CVE-2017-4916) affecting Workstation Pro/Player.

All VMware Workstation Pro/Player 12.x are affected.

Successful exploitation of the insecure library loading issue may allow unprivileged host users to escalate their privileges to root in a Linux host machine.

The NULL pointer dereference vulnerability exists in the vstor2 driver and may allow host users with normal user privileges to trigger a denial-of-service in a Windows host machine.

Workstation Pro/Player 12.5.6 fixes all these issues.

VMware would like to thank Jann Horn of Google Project Zero and Borja Merino for reporting these issues to us.

Patch Tuesday Overview – February 2013

For this month’s Patch Tuesday Microsoft released 12 bulletins of which five were rated as Critical and seven as Important updates, addressing a total of 57 vulnerabilities across Internet Explorer, .NET Framework, Office, Windows and Exchange Server.

For those who need to prioritize deployments, there are 3 security bulletins that will need to be addressed right away.

MS13-009 addresses 13 issues across all supported versions of Internet Explorer and MS13-010 addresses issues in the Vector Markup Language (VML) which is used by all versions of Internet Explorer. Both of these issues could allow Remote Code Execution if a user viewed a specially crafted webpage using Internet Explorer.

MS13-020 affecting Windows XP resolves an issue in Microsoft Windows Object Linking and Embedding (OLE) Automation which could allow Remote Code Execution if a user opens a malicious RTF file with an embedded ActiveX control in either Word or WordPad.

In addition to the above mentioned bulletins, for the second time in less than a week, both Microsoft and Adobe released Critical-class bulletins (KB2805940 and APSB13-05) to update Flash Players. These updates address at least 16 distinct vulnerabilities including buffer overflow and use-after-free vulnerabilities that could lead to Code Execution.

All the above mentioned bulletins are now available for deployment via VMware vCenter Configuration Manager (VCM).
