New Windows Zero-Day Bug Helps Delete Any File, Exploit Available (bleepingcomputer.com)

An anonymous reader quotes a report from Bleeping Computer: Proof-of-concept code for a new zero-day vulnerability in Windows has been released by a security researcher before Microsoft was able to release a fix. The code exploits a vulnerability that allows deleting without permission any files on a machine, including system data, and it has the potential to lead to privilege escalation. The vulnerability could be used to delete application DLLs, thus forcing the programs to look for the missing libraries in other places. If the search reaches a location that grants write permission to the local user, the attacker could take advantage by providing a malicious DLL.

The problem is with Microsoft Data Sharing Service, present in Windows 10, Server 2016 and 2019 operating systems, which provides data brokering between applications. Will Dormann, a vulnerability analyst at CERT/CC, tested the exploit code successfully on a Windows 10 operating system running the latest security updates. Behind the discovery is a researcher using the online alias SandboxEscaper, also responsible for publicly sharing in late August another security bug in Windows Task Scheduler component.
Microsoft hasn't addressed the issue, but there is a temporary fix available through the oPatch platform. "A micropatch candidate was ready seven hours after the zero-day vulnerability announcement, and it blocked the exploit successfully," reports Bleeping Computer. "oPatch now delivers the stable version of the micropatch for fully updated Windows 10 1803.

    1969: A Year of Bombings

    The 1969 bombings were part of a wave of similar episodes across the nation that spurred fear and anxiety. (One study found that from January 1969 to October 1970, there were about 370 bombings - most of them minor - in New York, an average of more than one every other day.)

    And let's not forget celebrated leftist and likely Obama ghostwriter Bill Ayers:

    After the Greenwich Village townhouse explosion in 1970, in which Weatherman member Ted Gold, Ayers's close friend Terry Robbins, and Ayers's girlfriend, Diana Oughton, were killed when a nail bomb being assembled in the house exploded, Ayers and several associates evaded pursuit by law enforcement officials. Kathy Boudin and Cathy Wilkerson survived the blast. Ayers was not facing criminal charges at the time, but the federal government later filed charges against him.[7] Ayers participated in the bombings of New York City Police Department headquarters in 1970, the United States Capitol building in 1971, and the Pentagon in 1972, as he noted in his 2001 book, Fugitive Days. Ayers writes:

    Although the bomb that rocked the Pentagon was itsy-bitsy—weighing close to two pounds—it caused 'tens of thousands of dollars' of damage. The operation cost under $500, and no one was killed or even hurt.[19]

    After the bombing, Ayers became a fugitive. During this time, Ayers and fellow member Bernardine Dohrn married and remained fugitives together, changing identities, jobs and locations.

    Nevermind last year's shooting of the House Majority Whip by a TDS-addled LEFTIST Bernie Bro shouting "This is for health care!!!"
