Vulnerability Information
Multiple Microsoft Office Memory Corruption Vulnerabilities
Microsoft Office 2015 Cracked
Remote code execution vulnerabilities exist in Microsoft Office software when the Office software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. The file could then, for example, take actions on behalf of the logged-on user with the same permissions as the current user. Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software.
In an email attack scenario an attacker could exploit the vulnerabilities by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerabilities. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince them to open the specially crafted file.
The security update addresses the vulnerabilities by correcting how Microsoft Office handles files in memory.
The following tables contain links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:
| Vulnerability title | CVE number | Publicly disclosed | Exploited |
| Microsoft Office Memory Corruption Vulnerability | CVE-2015-1642 | No | Yes |
| Microsoft Office Memory Corruption Vulnerability | CVE-2015-2467 | No | No |
| Microsoft Office Memory Corruption Vulnerability | CVE-2015-2468 | No | No |
| Microsoft Office Memory Corruption Vulnerability | CVE-2015-2469 | No | No |
| Microsoft Office Memory Corruption Vulnerability | CVE-2015-2477 | No | No |
Microsoft Office Remote Code Execution Vulnerability – CVE-2015-2466
A remote code execution vulnerability exists in Microsoft Office software when the Office software fails to properly validate templates. An attacker who successfully exploited this vulnerability could run arbitrary code in the context of the current user. Exploitation of this vulnerability requires that a user open a specially crafted template file with an affected version of Microsoft Office software.
An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
In an email attack scenario an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file.
In a web-based attack scenario an attacker could host a website or file share (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. An attacker would have no way to force users to visit the website or file share. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince them to open the specially crafted file.
Alternatively, an attacker could launch a “Man-in-the-middle” attack (intercept the traffic between source and destination) and modify the template contents to include malicious code.
The security update addresses the vulnerability by correcting how Office validates office templates prior to use.
Microsoft received information about the vulnerability through coordinated vulnerability disclosure. When this security bulletin was issued, Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers.

Microsoft has not identified any mitigating factors for this vulnerability.
Workarounds
Microsoft has not identified any workarounds for this vulnerability.
Microsoft Office Integer Underflow Vulnerability – CVE-2015-2470
A remote code execution vulnerability exists when Office decreases an integer value beyond its intended minimum value. Exploitation of this vulnerability requires that a user open a specially crafted Office file with an affected version of Microsoft Office software.
An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
In an email attack scenario an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file.
In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince them to open the specially crafted file.
The security update addresses the vulnerability by correcting how Office handles integer bounds checking.

Vulnerability Information
Excel Remote Code Execution Vulnerability - CVE-2015-0063
A remote code execution vulnerability exists in Microsoft Excel that is caused when Excel improperly handles objects in memory while parsing specially crafted Office files. This could corrupt system memory in such a way as to allow an attacker to execute arbitrary code.
An attacker who successfully exploited this vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Excel. In an email attack scenario an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains the specially crafted file that is designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to visit it, typically by getting them to click a link in an email message or Instant Messenger message, and then convince them to open the specially crafted file.
The security update addresses the vulnerability by correcting how Microsoft Excel parses files. Systems where affected Microsoft Office software is used, including workstations and terminal servers, are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.
Microsoft received information about the vulnerability through coordinated vulnerability disclosure. When this security bulletin was issued, Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers.
