CVE-2020-27348 – snapcraft may build snaps with incorrect LD_LIBRARY_PATH
https://notcve.org/view.php?id=CVE-2020-27348
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 • https://bugs.launchpad.net/bugs/1901572 https://github.com/snapcore/snapcraft/pull/3345 https://usn.ubuntu.com/usn/usn-4661-1 • CWE-427: Uncontrolled Search Path Element •

CVE-2020-16123 – Bypass of snapd pulseaudio restrictions
https://notcve.org/view.php?id=CVE-2020-16123
An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. This could be exploited by an attacker to expose sensitive information. Fixed in 1:13.99.3-1ubuntu2, 1:13.99.2-1ubuntu2.1, 1:13.99.1-1ubuntu3.8, 1:11.1-1ubuntu7.11, and 1:8.0-0ubuntu3.15. Un parche específico de Ubuntu en PulseAudio creó una condición de carrera en la que el módulo de política instantánea presentaría un fallo al identificar una conexión de cliente desde un complemento como proveniente de un complemento si faltaba SCM_CREDENTIALS, lo que permite que el complemento se conecte a PulseAudio sin el confinamiento adecuado. Un atacante podría explotar esto para exponer información confidencial. • https://launchpad.net/bugs/1895928 https://ubuntu.com/USN-4640-1 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
