New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 7.4
SynopsisAn application installed on the remote host is affected by multiple vulnerabilities.
DescriptionThe Microsoft Office application installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :
- An information disclosure vulnerability exists in the the Click-to-Run (C2R) components due to improper handling of objects in memory. An authenticated, remote attacker can exploit this, via a specially crafted application, to obtain sensitive information and thereby bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2016-0137)
- An information disclosure vulnerability exists due to Visual Basic macros improperly exporting a user's private key from the certificate store while saving a document.
An unauthenticated, remote attacker can exploit this, by convincing a user to provide the saved document, to gain access to the user's private key. (CVE-2016-0141)
- Multiple remote code execution vulnerabilities exist in Microsoft Office software due to improper handling of objects in memory. A remote attacker can exploit these, by convincing a user to open a specially crafted Office file, to execute arbitrary code in the context of the current user. (CVE-2016-3357, CVE-2016-3358, CVE-2016-3359, CVE-2016-3360, CVE-2016-3361, CVE-2016-3362, CVE-2016-3363, CVE-2016-3364, CVE-2016-3365, CVE-2016-3381)
- A spoofing vulnerability exists in Microsoft Outlook due to a failure to conform to RFC2046 and properly identify the end of a MIME attachment. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted email attachment, to cause antivirus or antispam security features to fail. (CVE-2016-3366)
