MS15-070: Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (3072620)

High Nessus Plugin ID 84739


The remote Windows host is affected by multiple vulnerabilities.


The remote Windows host has a version of Microsoft Office, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, SharePoint Server, or Microsoft Office Compatibility Pack installed that is affected by multiple vulnerabilities :

- An ASLR bypass vulnerability exists in Microsoft Excel due to memory being released in an unintended manner. A remote attacker can exploit this by convincing a user to open a specially crafted Excel (.xls) file, allowing the attacker to more reliably predict the memory offsets of specific instructions in a given call stack. The attacker can then utilize this information to more easily exploit additional vulnerabilities.

- Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. A remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2015-2376, CVE-2015-2377, CVE-2015-2379, CVE-2015-2380, CVE-2015-2415, CVE-2015-2424)

- A remote code execution vulnerability exists in Microsoft excel due to improper handling of the loading of dynamic link library (DLL) files. A remote attacker can exploit this vulnerability by placing a specially crafted DLL file in the user's current working directory and then convincing the user to launch a program designed to load the DLL, resulting in the execution of arbitrary code in the context of the current user.
