Description
A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection.
Analysis
Tar archive extraction allows hidden file injection by local authenticated users through crafted malicious archives, bypassing pre-extraction inspection mechanisms and enabling introduction of attacker-controlled files. The vulnerability affects Red Hat Enterprise Linux versions 6 through 10, requires local access and user interaction (extraction action), and presents a moderate integrity risk (CVSS 5.0) with no confirmed active exploitation or public proof-of-concept at time of analysis.
