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\n**Do not follow links provided by unknown or untrusted sources.** \nWeb users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources.

(CVE-2018-8280, CVE-2018-8290)\n\n - An elevation of privilege vulnerability exists in\n Windows when the Windows kernel-mode driver fails to\n properly handle objects in memory. An attacker who\n successfully exploited this vulnerability could run\n arbitrary code in kernel mode. An attacker could then\n install programs; view, change, or delete data; or\n create new accounts with full user rights.\n (CVE-2018-8282)\n\n - A denial of service vulnerability exists when Windows\n improperly handles File Transfer Protocol (FTP)\n connections. An attacker who successfully exploited the\n vulnerability could cause a target system to stop\n responding.

An attacker who\n successfully exploited the vulnerability could gain the\n same user rights as the current user.

Users whose accounts are configured to have\n fewer user rights on the system could be less impacted\n than users who operate with administrative user rights.\n (CVE-2018-8284)\n\n - An elevation of privilege vulnerability exists when\n Windows fails a check, allowing a sandbox escape. An\n attacker who successfully exploited the vulnerability\n could use the sandbox escape to elevate privileges on an\n affected system. This vulnerability by itself does not\n allow arbitrary code execution. However, the\n vulnerability could allow arbitrary code to run if an\n attacker uses it in combination with another\n vulnerability, such as a remote code execution\n vulnerability or another elevation of privilege\n vulnerability, that can leverage the elevated privileges\n when code execution is attempted. The security update\n addresses the vulnerability by correcting how Windows\n file picker handles paths.

An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights,\" Microsoft explains. \n \nOne of these critical flaws (CVE-2018-8327), reported by researchers at Casaba Security, also affects PowerShell Editor Services that could allow a remote attacker to execute malicious code on a vulnerable system. \n \nHere's below you can find a brief list of all critical vulnerabilities Microsoft has patched this month in its various products: \n\n\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8242)\n * Edge Memory Corruption Vulnerability (CVE-2018-8262)\n * Edge Memory Corruption Vulnerability (CVE-2018-8274)\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8275)\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8279)\n * Chakra Scripting Engine Memory Corruption Vulnerability (CVE-2018-8280)\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8283)\n * Chakra Scripting Engine Memory Corruption Vulnerability (CVE-2018-8286)\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8288)\n * Chakra Scripting Engine Memory Corruption Vulnerability (CVE-2018-8290)\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8291)\n * Chakra Scripting Engine Memory Corruption Vulnerability (CVE-2018-8294)\n * Scripting Engine Memory Corruption Vulnerability (CVE-2018-8296)\n * Chakra Scripting Engine Memory Corruption Vulnerability (CVE-2018-8298)\n * Microsoft Edge Memory Corruption Vulnerability (CVE-2018-8301)\n * Microsoft Edge Information Disclosure Vulnerability (CVE-2018-8324)\n * PowerShell Editor Services Remote Code Execution Vulnerability (CVE-2018-8327)\n \n\n\n### Important Patch Updates for Microsoft Products\n\n \nBesides this, Microsoft has also addressed 34 important flaws categorized as below: \n \n\n\n * Microsoft Edge\u2014Remote code execution (RCE), Information disclosure, spoofing, and security feature bypass flaws\n * Microsoft Internet Explorer (IE)\u2014 RCE and security feature bypass flaws\n * MS Office (Powerpoint, Word, Excel, Access, Lync, Skype)\u2014security feature bypass, RCE, and elevation of privilege flaws\n * Windows 10, 8.1, 7 and Server 2008, 2012, 2016\u2014Denial of Service, security feature bypass, elevation of privilege flaws\n * Microsoft .NET Framework\u2014Elevation of privilege and RCE flaws\n * Microsoft SharePoint\u2014Elevation of Privilege, and RCE flaws\n * ChakraCore\u2014RCE, and security feature bypass vulnerabilities\n * Microsoft Visual Studio\u2014RCE flaw\n * Expression Blend 4\u2014RCE flaw\n * ASP .NET\u2014security feature bypass flaws\n * Mail, Calendar, and People in Windows 8.1 App Store\u2014information disclosure flaw\n \nBesides this, Microsoft has also pushed security updates to patch vulnerabilities in Adobe products, details of which you can get through a [separate article posted](<https://thehackernews.com/2018/07/adobe-patch-update-july.html>) today. \n \nUsers are strongly advised to apply security patches as soon as possible to keep hackers and cybercriminals away from taking control of their computers. \n \nFor installing security updates, simply head on to Settings \u2192 Update &amp; security \u2192 Windows Update \u2192 Check for updates, or you can install the updates manually. \n", "modified": "2018-07-10T18:53:22", "published": "2018-07-10T18:47:00", "id": "THN:482268607F3476C1920BBF880270C854", "href": "https://thehackernews.com/2018/07/microsoft-security-patch-update.html", "type": "thn", "title": "Microsoft Releases Patch Updates for 53 Vulnerabilities In Its Software", "cvss": {"score": 0.0, "vector": "NONE"}}], "kaspersky": [{"lastseen": "2020-09-02T11:42:03", "bulletinFamily": "info", "cvelist": ["CVE-2018-8297", "CVE-2018-8276", "CVE-2018-8275", "CVE-2018-8291", "CVE-2018-0949", "CVE-2018-8289", "CVE-2018-8280", "CVE-2018-8279", "CVE-2018-8288", "CVE-2018-8278", "CVE-2018-8287", "CVE-2018-8325", "CVE-2018-8290", "CVE-2018-8262", "CVE-2018-8296", "CVE-2018-8324", "CVE-2018-8294", "CVE-2018-8125", "CVE-2018-8301", "CVE-2018-8286", "CVE-2018-8274", "CVE-2018-8242"], "description": "### *Detect date*:\n07/10/2018\n\n### *Severity*:\nWarning\n\n### *Description*:\nMultiple serious vulnerabilities were found in Microsoft Internet Explorer and Edge.

"description": "\n\nEarlier this week, I wrote a [blog](<https://blog.trendmicro.com/zero-day-initiative-a-1h2018-recap/>) covering a couple of the statistics from the Zero Day Initiative\u2019s (ZDI) first half of 2018. One of the stats that I didn\u2019t cover is the increasing focus on enterprise applications. The team is seeing consistent growth in submissions of Microsoft and Apple vulnerabilities, but now they\u2019re also seeing an increase of submissions in virtualization software vulnerabilities from the likes of VMware and Oracle. With a 33% increase in published advisories compared to 2017, the ZDI has their hands full. With more than 500 new researchers registering to participate in the program this year, the internal ZDI team is growing as well to accommodate this growth. 2018 may just be the biggest year yet for ZDI!\n\nIn case you missed it, you can read Brian Gorenc\u2019s [blog](<https://www.thezdi.com/blog/2018/7/9/checking-in-a-look-back-at-the-first-half-of-2018>) covering the detailed stats from the ZDI\u2019s first half of 2018.\n\n**Microsoft Security Updates**\n\nThis week\u2019s Digital Vaccine\u00ae (DV) package includes coverage for Microsoft updates released on or before July 10, 2018. It was another big month for Microsoft with 53 security patches covering both browsers (Internet Explorer, Edge), ChakraCore, Windows, .NET Framework, ASP.NET, PowerShell, Visual Studio, and Microsoft Office and Office Services. Of these 53 CVEs, 18 are listed as Critical, 33 are rated Important, one is rated as Moderate, and one is rated as Low in severity.\n\nFive CVEs in this month\u2019s Microsoft update came through the Zero Day Initiative:\n\n| \n\n * [CVE-2018-8242](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8242>)\n * [CVE-2018-8274](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8274>)\n * [CVE-2018-8275](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8275>)\n * [CVE-2018-8282](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8282>)\n * [CVE-2018-8307](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8307>) \n---|--- \n| \n \nThe following table maps Digital Vaccine filters to Microsoft\u2019s updates.
