Critical Ubuntu User Namespace Bypass Exploits Discovered

Critical Ubuntu User Namespace Bypass Exploits Discovered

Qualys researchers have uncovered three critical security bypasses in Ubuntu 23.10 and 24.04's unprivileged user namespace restrictions. These bypasses, leveraging the aa-exec tool, busybox shell, and LD_PRELOAD technique, allow local attackers to create user namespaces with full administrative privileges, potentially exploiting kernel vulnerabilities. Canonical acknowledges these as limitations of their AppArmor defense, not vulnerabilities, and recommends administrative hardening steps such as enabling kernel.apparmor_restrict_unprivileged_unconfined=1 to mitigate the risks.

Microsoft's New Office Startup Booster: Faster Loading, But With a Catch

Microsoft is rolling out a new Windows scheduled task called 'Startup Boost' in May to speed up Office app loading. This background task preloads performance enhancements but only runs on systems with 8GB RAM and 5GB free disk space, disabling automatically in Energy Saver mode. Users can disable it in Office settings, but the Office installer re-enables it with each update. While designed to improve launch times, its automatic re-enablement might annoy some users.

Oracle Cloud Breach: 6 Million User Data Allegedly Compromised

Cybersecurity firm BleepingComputer reports a hacker claiming to have breached Oracle Cloud servers, stealing authentication data for 6 million users. Oracle denies a breach, but BleepingComputer has confirmed the validity of data samples from multiple affected companies. The hacker released databases, LDAP data, and over 140,000 allegedly compromised domains. Investigations suggest exploitation of a vulnerability (CVE-2021-35587) in Oracle Fusion Middleware 11g. Despite Oracle's denial, evidence points to a significant security lapse, raising concerns about Oracle Cloud security.

Urgent: Update Your Firefox Browser Before March 14th!

Mozilla is urging Firefox users to update their browsers to version 128 or later (or ESR 115.13 or later) before March 14th, 2025, to avoid significant security risks. A critical root certificate is expiring, rendering add-ons unusable and potentially exposing users to malicious add-ons, fraudulent websites, and compromised password alerts. Failure to update could lead to severe performance issues and security vulnerabilities. The update affects Windows, Android, Linux, and macOS users, but not iOS. While older versions might still function, Mozilla strongly advises updating for optimal security and performance.

Windows Update Bricking USB Printers: Random Text Mayhem

Microsoft has acknowledged that recent Windows updates (KB5050092 and later, released since January 29th, 2025) are causing some dual-mode USB printers (supporting both USB Print and IPP over USB) to print random gibberish. This includes network commands and unusual characters. Windows 10 22H2 and Windows 11 22H2/23H2 are affected; Windows 11 24H2 is not. Microsoft has fixed this via Known Issue Rollback (KIR), and the fix will also automatically roll out in a future update. For enterprise environments, IT admins need to install and configure specific group policies to resolve the issue on affected devices.

Massive ESP32 Chip Flaw: Undocumented Backdoor Found in Over 1 Billion Devices

Researchers have uncovered a critical vulnerability in the widely used ESP32 microchip, affecting over a billion devices. 29 undocumented commands act as a backdoor, enabling attackers to spoof trusted devices, access data without authorization, pivot to other network devices, and establish persistent access. This vulnerability poses significant risks to IoT security, particularly when combined with existing root access or malicious firmware. The discovery, made by Tarlogic Security using a newly developed cross-platform Bluetooth driver, highlights the importance of comprehensive security testing in widely deployed hardware. Espressif, the manufacturer, has yet to publicly comment.

WinRAR 7.10 has been released, boasting numerous improvements including larger memory pages for performance boosts, a much-requested dark mode, and a redesigned settings interface. A standout feature is its enhanced privacy controls. Users can now fine-tune how information from the Mark-of-the-Web (MoTW) is propagated, with a default setting that only retains the security zone value, stripping potentially revealing URLs and IP addresses from extracted files. While this might impact digital forensics, it's a welcome addition for privacy-conscious users.

Brave Browser's New Custom Scriptlets: Take Control of Your Browsing Experience

Brave Browser version 1.75 introduces 'custom scriptlets' for desktop users, allowing advanced users to inject their own JavaScript into websites for deep customization. Similar to Tampermonkey and Greasemonkey, this feature enables users to create scripts modifying website functionality. Initially developed for debugging Brave's ad blocker, its value led to its release. Custom scriptlets enhance privacy, security, and usability by blocking trackers, customizing appearance, and improving accessibility. However, caution is advised as untrusted scripts pose risks. The feature is located in `brave://settings/shields/filters` and requires enabling 'Developer mode'.

Critical Apple CPU Side-Channel Flaws Steal Browser Data

Researchers have uncovered new side-channel vulnerabilities, FLOP and SLAP, in Apple's M-series and A-series processors. These flaws allow remote attackers to steal sensitive data from web browsers via malicious websites, bypassing browser sandboxing. The vulnerabilities stem from faulty speculative execution, exploiting the CPU's mispredictions to leak information like emails, location history, and more. Apple is aware and plans to address the issue, but patches aren't yet available. Disabling JavaScript is a temporary mitigation, but impacts website functionality.
