An attacker can leverage this issue to obtain sensitive information that may aid in further attacks.\n\n### Technologies Affected\n\n * Microsoft Outlook 2016 Click-to-Run (C2R) for 32-bit edition \n * Microsoft Outlook 2016 Click-to-Run (C2R) for 64-bit edition \n\n### Recommendations\n\n**Block external access at the network boundary, unless external parties require service.** \nIf global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.\n\n**Run all software as a nonprivileged user with minimal access rights.** \nRunning server processes within a restricted environment using facilities such as chroot or jail may limit the consequences of successful exploits.\n\n**Deploy network intrusion detection systems to monitor network traffic for malicious activity.** \nDeploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.\n\nUpdates are available. Please see the references or vendor advisory for more information.\n", "modified": "2017-12-12T00:00:00", "published": "2017-12-12T00:00:00", "id": "SMNTC-102105", "href": "https://www.symantec.com/content/symantec/english/en/security-center/vulnerabilities/writeup.html/102105", "type": "symantec", "title": "Microsoft Office Outlook CVE-2017-11939 Information Disclosure Vulnerability", "cvss": {"score": 4.0, "vector": "AV:NETWORK/AC:LOW/Au:SINGLE_INSTANCE/C:PARTIAL/I:NONE/A:NONE/"}}], "mscve": [{"lastseen": "2021-03-18T19:17:20", "bulletinFamily": "microsoft", "cvelist": ["CVE-2017-11939"], "description": "An information disclosure vulnerability exists when Microsoft Outlook fails to enforce copy/paste permissions on DRM-protected emails.

Unfortunately, when you don\u2019t live in the town of your favorite team, you can be subject to blackout rules. So, my husband and I decided to purchase NFL Sunday Ticket from DirecTV. Fast forward to a couple of years ago \u2013 I wanted to watch my team play, but the channel that the game was supposed to be on was showing another game featuring my least favorite team instead. Needless to say, I was a little upset. I called DirecTV and I wasn\u2019t shy about my feelings on the situation. The customer service representative put me on hold to figure out the problem. Why wasn\u2019t I able to see my game? The game was already over. I\u2019m sure the team at DirecTV had a big laugh over my mistake, but I owned up to it and apologized to the representative.\n\nWhen a vulnerability is submitted to the Zero Day Initiative (ZDI), the affected vendor is given 120 days to take action to patch the vulnerability. If the deadline is not met, the ZDI will publicly disclose the vulnerability in accordance with its disclosure policy. Earlier this week, the Zero Day Initiative (ZDI) published a zero-day vulnerability as a result of a vendor not patching a vulnerability. One of our internal researchers, [Ricky Lawshae](<https://twitter.com/HeadlessZeke>), submitted a vulnerability to the Zero Day Initiative in mid-June of this year involving equipment that DirecTV uses with its Wireless Genie devices. The affected equipment is a Linksys WVBR0-25 which is used as a wireless video bridge. Ricky reviewed the scripts running on the Linksys device and found one that he could to inject additional commands. He was able to implement a root shell on the box in less than 30 seconds by exploiting this command injection vulnerability, which ultimately granted him full remote unauthenticated administrator control over the device. The ZDI attempted to contact the vendor several times regarding the vulnerability but never received a reply. The ZDI informed Linksys that the vulnerability would be published on December 12, 2017. You can read [Ricky\u2019s blog](<https://www.zerodayinitiative.com/blog/2017/12/13/remote-root-in-directvs-wireless-video-bridge-a-tale-of-rage-and-despair>) to get more details on this vulnerability as well as view a video of the exploit in action.**Microsoft Update**\n\nThis week\u2019s Digital Vaccine\u00ae (DV) package includes coverage for Microsoft updates released on or before December 12, 2017. Security patches were released by Microsoft covering Internet Explorer (IE), Edge, Windows, Office, SharePoint, and Exchange. Three of the Microsoft CVEs came through the ZDI program.

Successful exploitation of this vulnerability would require an attacker to send victims a specially crafted email containing a malicious link. \n \n\n\n### CVE-2017-11934 - Microsoft PowerPoint Information Disclosure Vulnerability\n\n \nAn information disclosure vulnerability has been identified that affects Microsoft Office. This vulnerability manifests due to Microsoft Office improperly disclosing contents in memory. This vulnerability could be leveraged by an attacker to obtain sensitive information that could be used to launch additional attacks against a target system. Successful exploitation of this vulnerability would require an attacker to send a specially crafted file to a victim and convince them to open the file. \n \n\n\n### CVE-2017-11935 - Microsoft Excel Remote Code Execution Vulnerability\n\n \nAn arbitrary code execution vulnerability has been identified in Microsoft Excel which manifests as a result of improperly handling objects in memory. An attacker could exploit this vulnerability by creating a specially crafted Excel document which triggers the vulnerability. Successful exploitation would allow an attacker to execute arbitrary code in the context of the current user. Scenarios where this could occur include email-based attacks or attacks where users download malicious files off of a site hosting user-created content (DropBox, OneDrive, Google Drive). \n \n\n\n### CVE-2017-11936 - Microsoft SharePoint Elevation of Privilege Vulnerability\n\n \nA privilege escalation vulnerability has been identified in Microsoft SharePoint Server that could potentially allow an attacker to impersonate a user and perform restricted actions. This vulnerability manifests due to SharePoint improperly sanitizing specially crafted web requests. An authenticated user who exploits this vulnerability could proceed to perform a cross-site scripting attack to cause other users to execute arbitrary JavaScript in the context of that user. This could then allow an attacker to read content, change permissions, or inject other malicious content on behalf of that user if permitted. \n \n\n\n### CVE-2017-11939 - Microsoft Office Information Disclosure Vulnerability\n\n \nAn information disclosure vulnerability has been identified in Microsoft Office that could leak a user's private key. This vulnerability manifests as a result of Visual Basic macros in Office incorrectly exporting a user's private key from the certificate store while saving a document. Note that an attacker would need to exploit another vulnerability or socially engineer the user to obtain the document containing the leaked private key in order to leverage it. \n \n\n\n## Coverage\n\n \nIn response to these vulnerability disclosures, Talos is releasing the following Snort rules that detect attempts to exploit them.
