Description

A flaw was found in binutils. The copy_section function in binutils/objcopy.c is susceptible to a heap-based buffer overflow due to improper bounds checking during data copying. This flaw allows a local attacker to provide a specially crafted file. This manipulation can lead to a denial of service.

Statement

The Moderate severity rating is based on the requirement of local access for an attacker to exploit this vulnerability. Although a successful exploit could lead to heap-based buffer overflow, the prerequisite of having an established presence on the system lowers the risk compared to remotely exploitable vulnerabilities. Red Hat products widely use GNU Binutils, a fundamental set of programming tools for creating and managing binary files, which makes this a component of significant interest. However, the attack vector significantly mitigates the immediate risk to systems.
