Description:
Two vulnerabilities were reported in Windows JScript/VBScript Engine. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can obtain potentially sensitive information on the target system.
A remote user can create specially crafted content that, when loaded by the target user, will trigger a memory corruption error in the VBScript engine and execute arbitrary code on the target user's system [CVE-2015-6136]. This can also be exploited via an ActiveX control marked as "safe for initialization" and contained in an application or Microsoft Office document that hosts the rendering engine.
A remote user can create specially crafted content that, when loaded by the target user, will trigger a flaw in the VBScript engine and access potentially sensitive information from memory on the target user's system [CVE-2015-6135].
An anonymous researcher (via HP's Zero Day Initiative), Simon Zuckerbraun (via HP's Zero Day Initiative), Yuki Chen of Qihoo 360Vulcan Team, and chenxuebin@360.cn reported these vulnerabilities.
