C++ (Cpp) __sanitize_environment_variables Exemples

Exemple #1

Fichier : libc_init_common.cpp Projet : jackLi93/platform_bionic

void __libc_init_AT_SECURE(KernelArgumentBlock& args) {
  __libc_auxv = args.auxv;

  // Check that the kernel provided a value for AT_SECURE.
  bool found_AT_SECURE = false;
  for (ElfW(auxv_t)* v = __libc_auxv; v->a_type != AT_NULL; ++v) {
    if (v->a_type == AT_SECURE) {
      found_AT_SECURE = true;
      break;
    }
  }
  if (!found_AT_SECURE) __early_abort(__LINE__);

  if (getauxval(AT_SECURE)) {
    // If this is a setuid/setgid program, close the security hole described in
    // https://www.freebsd.org/security/advisories/FreeBSD-SA-02:23.stdio.asc
    __nullify_closed_stdio();

    __sanitize_environment_variables(args.envp);
  }

  // Now the environment has been sanitized, make it available.
  environ = args.envp;

  __initialize_personality();
}

Exemple #2

Fichier : linker_environ.cpp Projet : 10114395/android-5.0.0_r5

}

Exemple #3
