CVE-2026-4647
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se encontró una falla en la biblioteca BFD de GNU Binutils, un componente ampliamente utilizado para manejar archivos binarios como archivos objeto y ejecutables. El problema ocurre al procesar archivos objeto XCOFF especialmente manipulados, donde un valor de tipo de reubicación no se valida correctamente antes de ser utilizado. Esto puede causar que el programa lea memoria fuera de los límites previstos. Como resultado, las herramientas afectadas pueden bloquearse o exponer contenidos de memoria no deseados, lo que lleva a una denegación de servicio o a riesgos limitados de revelación de información."
