medium Nessus Plugin ID 305082
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- 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. (CVE-2026-5704)
Note that Nessus relies on the presence of the package as reported by the vendor.
