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') •

CVE-2020-15157 – containerd can be coerced into leaking credentials during image pull
https://notcve.org/view.php?id=CVE-2020-15157
In containerd (an industry-standard container runtime) before version 1.2.14 there is a credential leaking vulnerability. If a container image manifest in the OCI Image format or Docker Image V2 Schema 2 format includes a URL for the location of a specific image layer (otherwise known as a “foreign layer”), the default containerd resolver will follow that URL to attempt to download it. In v1.2.x but not 1.3.0 or later, the default containerd resolver will provide its authentication credentials if the server where the URL is located presents an HTTP 401 status code along with registry-specific HTTP headers. If an attacker publishes a public image with a manifest that directs one of the layers to be fetched from a web server they control and they trick a user or system into pulling the image, they can obtain the credentials used for pulling that image. In some cases, this may be the user's username and password for the registry. • https://github.com/containerd/containerd/releases/tag/v1.2.14 https://github.com/containerd/containerd/security/advisories/GHSA-742w-89gc-8m9c https://usn.ubuntu.com/4589-1 https://usn.ubuntu.com/4589-2 https://www.debian.org/security/2021/dsa-4865 https://access.redhat.com/security/cve/CVE-2020-15157 https://bugzilla.redhat.com/show_bug.cgi?id=1888248 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •
