  Cybersecurity researchers on Tuesday disclosed details of an unpatched vulnerability in macOS Finder that could be abused by remote adversaries to trick users into running arbitrary commands on the machines. "A vulnerability in macOS Finder allows files whose extension is inetloc to execute arbitrary commands, these files can be embedded inside emails which if the user clicks on them will execute the commands embedded inside them without providing a prompt or warning to the user," SSD Secure Disclosure said in a write-up published today. Park Minchan, an independent security researcher, has been credited with reporting the vulnerability which affects macOS versions of Big Sur and prior.   The weakness arises due to the manner macOS processes INETLOC files — shortcuts to internet locations such as RSS feeds or Telnet connections containing username and password for SSH — resulting in a scenario that allows commands embedded in those files to be executed wi

    A day after Apple and Google rolled out urgent security updates, Microsoft has pushed software fixes as part of its monthly Patch Tuesday release cycle to plug 66 security holes affecting Windows and other components such as Azure, Office, BitLocker, and Visual Studio, including an actively exploited zero-day in its MSHTML Platform that came to light last week. Of the 66 flaws, three are rated Critical, 62 are rated Important, and one is rated Moderate in severity. This is aside from the 20 vulnerabilities in the Chromium-based Microsoft Edge browser that the company addressed since the start of the month. The most important of the updates concerns a patch for CVE-2021-40444 (CVSS score: 8.8), an actively exploited remote code execution vulnerability in MSHTML that leverages malware-laced Microsoft Office documents, with EXPMON researchers noting "the exploit uses logical flaws so the exploitation is perfectly reliable." Also addressed is a publicly d
