Microsoft Releases Out-of-Band Security Updates for PrintNightmare

Original release date: July 6, 2021

Microsoft has released out-of-band security updates to address a remote code execution (RCE) vulnerability—known as PrintNightmare (CVE-2021-34527)—in the Windows Print spooler service. According to the CERT Coordination Center (CERT/CC), “The Microsoft Windows Print Spooler service fails to restrict access to functionality that allows users to add printers and related drivers, which can allow a remote authenticated attacker to execute arbitrary code with SYSTEM privileges on a vulnerable system.”

The updates are cumulative and contain all previous fixes as well as protections for CVE-2021-1675. The updates do not include Windows 10 version 1607, Windows Server 2012, or Windows Server 2016—Microsoft states updates for these versions are forthcoming. Note: According to CERT/CC, “the Microsoft update for CVE-2021-34527 only appears to address the Remote Code Execution (RCE via SMB and RPC) variants of the PrintNightmare, and not the Local Privilege Escalation (LPE) variant.” See CERT/CC Vulnerability Note VU #383432 for workarounds for the LPE variant.

Supreme Court Overturns Overbroad Interpretation of CFAA, Protecting Security Researchers and Everyday Users

Electronic Frontier Foundation has long fought to reform vague, dangerous computer crime laws like the Computer Fraud and Abuse Act. In a month packed with Supreme Court decisions that could change the digital rights (and human rights) landscape, we’re gratified by the Court’s important decision in Van Buren. The Court acknowledged that overbroad application of the CFAA risks turning nearly any user of the Internet into a criminal based on arbitrary terms of service. We remember the tragic and unjust results of the CFAA’s misuse, such as the death of Aaron Swartz, and we will continue to fight to ensure that computer crime laws no longer chill security research, journalism, and other novel and interoperable uses of technology that ultimately benefit all of us.
