Descriptions

In some conditions, a snap package built by snapcraft includes the current directory in LD_LIBRARY_PATH, allowing a malicious snap to gain code execution within the context of another snap if both plug the home interface or similar. This issue affects snapcraft versions prior to 4.4.4, prior to 2.43.1+16.04.1, and prior to 2.43.1+18.04.1.

En algunas condiciones, un paquete snap creado por snapcraft incluye el directorio actual en LD_LIBRARY_PATH, permitiendo a un snap malicioso conseguir una ejecución de código dentro del contexto de otro snap si ambos conectan la interfaz de inicio o similar. Este problema afecta a Snapcraft versiones anteriores a 4.4.4, anteriores a 2.43.1+16.04.1 y anteriores a 2.43.1+18.04.1
