VMware Fixes Critical Security Issues in Workstation, Fusion, Horizon View

VMware has released software updates to address several security flaws affecting some of the company’s products.

VMware has released software updates to address several security flaws affecting some of the company’s products.

According to an advisory published by the company on Tuesday, Kostya Kortchinsky of the Google Security Team reported several memory manipulation issues affecting VMware Workstation, VMware Player, and the VMware Horizon View Client for Windows.

“VMware Workstation and Horizon Client TPView.ddl and TPInt.dll incorrectly handle memory allocation. On Workstation, this may allow a guest to execute code or perform a Denial of Service on the Windows OS that runs Workstation. In the case of a Horizon Client, this may allow a View desktop to execute code or perform a Denial of Service on the Windows OS that runs the Horizon Client,” the company said.

The vulnerabilities have been addressed with the release of Workstation versions 11.1.1 and 10.0.6, Player versions 7.1.1 and 6.0.6, and Horizon Client for Windows versions 3.4.0, 3.2.1 and 5.4.2.

VMware has also patched a denial-of-service (DoS) vulnerability affecting Workstation, Player, and Fusion. The vulnerability, caused by an input validation issue on an RPC command, can be exploited to cause a DoS condition on the guest operating system (32-bit), or on the host operating system (64-bit).

The flaw was reported by Peter Kamensky from Russia-based Digital Security, who was credited by VMware earlier this year for reporting a different DoS bug affecting Workstation, Player, and Fusion.

The recent DoS issue doesn’t affect Workstation 11.x and Player 7.x, and Fusion is only affected when running on OS X, VMware noted. The vulnerability has been patched with the release of VMware 10.0.5, Player 6.0.6, and Fusion versions 7.0.1 and 6.0.6.

The following CVE identifiers have been assigned to these vulnerabilities: CVE-2012-0897, CVE-2015-2336, CVE-2015-2337, CVE-2015-2338, CVE-2015-2339, CVE-2015-2340, and CVE-2015-2341.

In April, VMware announced the availability of updates for Horizon, vCenter, vCloud, vSphere, vFabric, NSX and vRealize products. The updates addressed Java SE Runtime Environment (JRE) vulnerabilities patched by Oracle in January.
