Microsoft Edge Chakra Scripting Engine CVE-2019-0770 Remote Memory Corruption Vulnerability
2019-03-12T00:00:00
ID SMNTC-107251 Type symantec Reporter Symantec Security Response Modified 2019-03-12T00:00:00
Description
Description
Microsoft Edge is prone to a remote memory-corruption vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the currently logged-in user. Failed attacks will cause denial of service conditions.
Technologies Affected
Microsoft Edge
Recommendations
Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy 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
Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Implement multiple redundant layers of security.
Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.
Updates are available. Please see the references or vendor advisory for more information.

The latest Patch Tuesday covers 64 vulnerabilities, 17 of which are rated \u201ccritical,\u201d 45 that are considered \u201cimportant\u201d and one \u201cmoderate\u201d and \u201clow\u201d vulnerability each. This release also includes two critical advisories \u2014 one covering security updates to Adobe Flash Player and another concerning SHA-2. \n \nThis month\u2019s security update covers security issues in a variety of Microsoft\u2019s products, including the VBScript scripting engine, Dynamic Host Configuration Protocol and the Chakra scripting engine. For coverage of these vulnerabilities, read the SNORT\u24c7 blog post [here](<https://blog.snort.org/2019/03/snort-rule-update-for-march-12-2019.html>). \n\n\n### Critical vulnerabilities\n\nMicrosoft disclosed 17 critical vulnerabilities this month, all of which we will highlight below. \n \n[CVE-2019-0592](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0592>) is a memory corruption vulnerability in the Chakra scripting engine that could allow an attacker to elevate their privileges. The bug lies in the way that the scripting engine handles objects in memory. In order to exploit this vulnerability, an attacker would need to trick a user into visiting a specially crafted, malicious web page in the Microsoft Edge web browser. \n \n[CVE-2019-0763](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0763>) is a remote code execution vulnerability that exists when the Internet Explorer web browser improperly handles objects in memory. An attacker could exploit this vulnerability by tricking a user into visiting a malicious web page while using Internet Explorer. \n \n[CVE-2019-0756](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0756>) is a remote code execution vulnerability in the Microsoft XML Core Services MSXML parser. An attacker can exploit this bug by tricking the user into opening a specially crafted website designed to invoke MSXML through a web browser. Eventually, the attacker would gain the ability to execute malicious code and take control of the user\u2019s system. \n \n[CVE-2019-0609](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0609>), [CVE-2019-0639](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0639>), [CVE-2019-0680](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0680>), [CVE-2019-0769](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0769>), [CVE-2019-0770](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0770>), [CVE-2019-0771](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0771>) and [CVE-2019-0773](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0773>) are all memory corruption vulnerabilities in Microsoft\u2019s scripting engine that exist due to the way Microsoft Edge handles objects in memory. An attacker could exploit these bugs to corrupt memory in a way that would allow them to execute arbitrary code in the context of the current user. A user would trigger this vulnerability if they visited a specially crafted, malicious web page in Edge. \n \n[CVE-2019-0784](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0784>) is a remote code execution vulnerability that exists due to the way ActiveX Data Objects (ADO) handle objects in memory. An attacker could exploit this bug by tricking a user into visiting a specially crafted, malicious web page in Internet Explorer. Alternatively, they could embed an ActiveX control marked \u201csafe for initialization\u201d in an application or Microsoft Office document that hosts the Internet Explorer rendering engine. \n \n[CVE-2019-0603](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0603>) is a remote code execution vulnerability in Windows Deployment Services TFTP Server. The bug lies in the way the server handles objects in memory. If an attacker were to exploit this vulnerability, they\u2019d gain the ability to execute arbitrary code with elevated permissions on a target system. \n \n[CVE-2019-0697](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0697>), [CVE-2019-0698](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0698>) and [CVE-2019-0726](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0726>) are remote code execution vulnerabilities in the Windows DHCP client. The vulnerability triggers when the client receives specially crafted DHCP responses to a client, potentially allowing an attacker to execute arbitrary code on the target machine. \n \n[CVE-2019-0666](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0666>) and [CVE-2019-0667](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0667>) are vulnerabilities in the VBScript engine that exist due to the way the engine handles objects in memory. An attacker could use these bugs to corrupt memory in a way that would allow them to execute arbitrary code in the context of the current user. A user could trigger these vulnerabilities by visiting an attacker-created website through Internet Explorer. An attacker could also provide them with an embedded ActiveX control marked \u201csafe for initialization\u201d in an application or Microsoft Office document that hosts the Internet Explorer rendering engine. \n\n\n### Important vulnerabilities\n\nThis release also contains 45 important vulnerabilities: \n\n\n *
