Descriptions
sudo_noexec.so in Sudo before 1.8.15 on Linux might allow local users to bypass intended noexec command restrictions via an application that calls the (1) system or (2) popen function.
Sudo_noexec.so en Sudo en versiones anteriores a 1.8.15 en Linux podría permitir a los usuarios locales evitar las restricciones de comandos noexec pretendidas a través de una aplicación que llama al (1) sistema o (2) a la función popen.
It was discovered that the sudo noexec restriction could have been bypassed if application run via sudo executed system() or popen() C library functions with a user supplied argument. A local user permitted to run such application via sudo with noexec restriction could use this flaw to execute arbitrary commands with elevated privileges.
