Critical Backdoor in XZ Utils - CVE-2024-3094

A critical vulnerability (CVE-2024-3094) has been identified in XZ Utils versions 5.6.0 and 5.6.1. This data compression utility is widely used in many operating systems, primarily Linux distributions. The vulnerability introduces a backdoor, potentially granting malicious actors full remote control of affected systems. Immediate action is required. XZ Utils is a command-line tool on Unix-like operating systems for file compression and decompression. It also includes a library (liblzma) that other software can use. The backdoor was discovered by a PostgreSQL developer at Microsoft. As of March 30, 2024, there's no evidence of active exploitation, but the situation is evolving.
