Microsoft has seen Vulnerability-related.DiscoverVulnerability its share of issues as of late , and now a seemingly simple patch is causing serious issues to certain laptops running the 2016 Anniversary Update . The update was originally released Vulnerability-related.PatchVulnerability to prevent a zero-day attack on IE . Per Microsoft , this was the issue being fixed Vulnerability-related.PatchVulnerability : A remote code execution vulnerability exists in Vulnerability-related.DiscoverVulnerability the way that the scripting engine handles objects in memory in Internet Explorer . The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user . An attacker who successfully exploited Vulnerability-related.DiscoverVulnerability the vulnerability could gain the same user rights as the current user . If the current user is logged on with administrative user rights , an attacker who successfully exploited Vulnerability-related.DiscoverVulnerability the vulnerability could take control of an affected system . An attacker could then install programs ; view , change , or delete data ; or create new accounts with full user rights . In a web-based attack scenario , an attacker could host a specially crafted website that is designed Attack.Phishing to exploit the vulnerability through Internet Explorer and then convince Attack.Phishing a user to view the website , for example , by sending Attack.Phishing an email . The security update addresses Vulnerability-related.PatchVulnerability the vulnerability by modifying how the scripting engine handles objects in memory . But now that fix is causing a pretty big problem of its own : it ’ s preventing certain laptops from booting . The affected machines are part of a pretty small bunch—only Lenovo laptops with less than 8 GB of RAM running the 2016 Anniversary Update ( 1607 ) —but it ’ s still a pretty bad problem to have . Fortunately , there ’ s a way to bypass the failed boot by restarting into the UEFI and disabling Secure Boot . It ’ s also noted that if BitLocker is enabled that you may have to go through BitLocker recovery after disabling Secure Boot . On the upside , Microsoft is working with Lenovo to correct Vulnerability-related.PatchVulnerability the issue and will release Vulnerability-related.PatchVulnerability a fix sometime in the future . I just wouldn ’ t count on it before the end of the year . Until then , be careful when updating devices , especially if they happen to be Lenovo laptops with limited RAM .
