Critical Windows bug fixed today is actively being exploited to hack users
Microsoft on Tuesday patched two Windows vulnerabilities that attackers are actively exploiting in the wild to install malicious apps on the computers of unwitting users.
The first vulnerability resides in the VBScript Engine included in all currently supported versions of Windows. A so coque iphone gratuit called use after free flaw involving the way the engine handles computer memory allows attackers to execute code of their choice that runs with givenchy coque iphone 6 the same system privileges chosen by the logged in user. When targeted users are logged in with administrative rights, attackers who exploit coque iphone adidas coque iphone xr protection militaire original the bug can coque iphone 5s couleur take complete control of the coque iphone 5se antichoc system. In the event users are logged in with more limited rights, attackers may still be able to escalate privileges by exploiting a separate vulnerability.
CVE 2018 8174, as the flaw is formally indexed, is being actively exploited by attackers, Microsoft officials said. The vulnerability was discovered by antivirus provider Kaspersky Lab, which then reported coque iphone xr tic et tac it to Microsoft. In the exploits observed by Kaspersky Lab:
Targets receive a malicious RTF Microsoft Office document
After being opened, the coque iphone emoji malicious document causes the second stage of the exploit to be downloaded in the form of coque iphone stussy an HTML page with malicious coque iphone 4s homer code
The coque transparente devant derriere iphone xr malicious code triggers the use after free memory corruption bug
Accompanying shellcode then downloads and executes a coque iphone 6 lebron james malicious payload
Kaspersky Lab security researcher Anton Ivanov wrote the following in an email:
This technique, until fixed, allowed criminals to coque iphone se amazone force Internet Explorer to load, no matter which browser one normally used further increasing an already huge attack surface. We urge organizations and private users to install recent nike coque iphone 7 patches immediately, as it won’t be long before exploits to this vulnerability make it to popular exploit kits and will be used not only by sophisticated threat actors but also by standard cybercriminals.
In an advisory published Tuesday, Microsoft officials said attackers could also exploit coque iphone 4s carrefour the vulnerability by hosting an exploit on a website coque iphone xr rose silicone or in website ads and tricking a target to view the malicious content with the IE browser. Neither coque iphone 6 plus moto Microsoft nor Kaspersky Lab provided details about who is exploiting the vulnerability, who is being exploited, or how widespread the exploits are. Microsoft rated CVE 2018 8174 “critical,” the company’s highest severity rating.
The second vulnerability is a privilege escalation flaw in the Win32k component of Windows. “An attacker who successfully magasin coque iphone 6 exploited this vulnerability could run arbitrary code in kernel mode,” Microsoft officials wrote in a separate advisory. “An attacker could then install programs; view, change, photobox coque iphone 6 or delete data; or create new accounts with full user rights.” The flaw is rated “important,” one level below “critical.” Microsoft didn’t provide details about the in the wild exploits.
In all, Microsoft issued 68 security bulletins on Tuesday as coque iphone 4 ananas part of its monthly patch release. Twenty one of the patches were rated critical, 45 were rated important, and two were rated as low severity. Other noteworthy bulletins patched remote code execution vulnerabilities in Microsoft’s Hyper V and Hyper V SMB and an Azure IoT SDK coque apple iphone xr cuir spoofing vulnerability.
