NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.
