The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

- A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of- bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service.
