CVE-2026-40499

radare2 prior to version 6.1.4 contains a command injection vulnerability in the PDB parser's print_gvars() function that allows attackers to execute arbitrary commands by embedding a newline byte in the PE section header name field. Attackers can craft a malicious PDB file with specially crafted section names to inject r2 commands that are executed when the idp command processes the file.

Summary		(es) radare2 anterior a la versión 6.1.4 contiene una vulnerabilidad de inyección de comandos en la función print_gvars() del analizador PDB que permite a los atacantes ejecutar comandos arbitrarios incrustando un byte de nueva línea en el campo de nombre del encabezado de sección PE. Los atacantes pueden crear un archivo PDB malicioso con nombres de sección especialmente diseñados para inyectar comandos r2 que se ejecutan cuando el comando idp procesa el archivo.
