The most common task facing system administrators is patching infrastructure. It's time consuming, it requires coordination with application teams and stakeholders, and it often must happen in segments over time. These complications make it difficult to maintain environmental consistency, which in turn can lead to instability, performance issues, and more time spent by operations staff. Using Red Hat Insights content templates to patch Red Hat Enterprise Linux (RHEL) helps limit the complexity of these activities while also increasing consistency across an IT estate.Define, instruct, and patch

A threat actor with ties to China has been attributed to a five-month-long intrusion targeting a Russian IT service provider, marking the hacking group's expansion to the country beyond Southeast Asia and South America. The activity, which took place from January to May 2025, has been attributed by Broadcom-owned Symantec to a threat actor it tracks as Jewelbug, which it said overlaps with

October's Microsoft Patch Tuesday fixes 170+ flaws, including 3 actively exploited zero-days and critical WSUS RCE (CVSS 9.8). Immediate patching is mandatory. Final free updates for Windows 10.

### Summary An SMTP Command Injection (CRLF Injection) vulnerability in Netty's SMTP codec allows a remote attacker who can control SMTP command parameters (e.g., an email recipient) to forge arbitrary emails from the trusted server. This bypasses standard email authentication and can be used to impersonate executives and forge high-stakes corporate communications. ### Details The root cause is the lack of input validation for Carriage Return (\r) and Line Feed (\n) characters in user-supplied parameters. The vulnerable code is in io.netty.handler.codec.smtp.DefaultSmtpRequest, where parameters are directly concatenated into the SMTP command string. For example, when SmtpRequests.rcpt(recipient) is called, a malicious recipient string containing CRLF sequences can inject a new, separate SMTP command. Because the injected commands are sent from the server's trusted IP, any resulting emails will likely pass SPF and DKIM checks, making them appear legitimate to the victim's email clien...

New research has uncovered that publishers of over 100 Visual Studio Code (VS Code) extensions leaked access tokens that could be exploited by bad actors to update the extensions, posing a critical software supply chain risk. "A leaked VSCode Marketplace or Open VSX PAT [personal access token] allows an attacker to directly distribute a malicious extension update across the entire install base,"

An estimated 100 million people live with facial differences. As face recognition tech becomes widespread, some say they’re getting blocked from accessing essential systems and services.

Microsoft on Tuesday released fixes for a whopping 183 security flaws spanning its products, including three vulnerabilities that have come under active exploitation in the wild, as the tech giant officially ended support for its Windows 10 operating system unless the PCs are enrolled in the Extended Security Updates (ESU) program. Of the 183 vulnerabilities, eight of them are non-Microsoft
