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 GNU Binutils. This vulnerability, a heap-based buffer overflow, specifically an out- of-bounds read, exists in the bfd linker component. An attacker could exploit this by convincing a user to process a specially crafted malicious XCOFF object file. Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service. (CVE-2026-3442)

Note that Nessus relies on the presence of the package as reported by the vendor.
