      "value": "mingw-w64 version 5.0.4 by default produces executables that opt in to ASLR, but are not compatible with ASLR. ASLR is an exploit mitigation technique used by modern Windows platforms. For ASLR to function, Windows executables must contain a relocations table. Despite containing the \"Dynamic base\" PE header, which indicates ASLR compatibility, Windows executables produced by mingw-w64 have the relocations table stripped from them by default. This means that executables produced by mingw-w64 are vulnerable to return-oriented programming (ROP) attacks. Windows executables generated by mingw-w64 claim to be ASLR compatible, but are not. Vulnerabilities in such executables are more easily exploitable as a result."

      "value": "mingw-w64 5.0.4 produce por defecto ejecutables que realizan opt in en ASLR, pero que no son compatibles con ASLR. ASLR es una t\u00e9cnica de mitigaci\u00f3n de exploits empleada en las plataformas Windows modernas. Para que ASLR funcione, los ejecutables de Windows deben contener una tabla de reubicaciones. Aunque contienen la cabecera PE \"Dynamic base\", que indica la compatibilidad con ASLR, los ejecutables de Windows producidos por mingw-w64 no cuentan con esta tabla por defecto. Esto significa que los ejecutables producidos por mingw-w64 son vulnerables a ataques ROP (Return-Oriented Programming). Los ejecutables de Windows generados por mingw-w64 deber\u00edan ser compatibles con ASLR, pero en realidad no lo son. Como resultado, las vulnerabilidades en estos ejecutables son m\u00e1s f\u00e1cilmente explotables."
