CVE-2024-5300

A flaw was found in Canonical snapd. The base AppArmor security profile configuration in snapd inadvertently allows strictly confined snap applications to bypass intended sandbox restrictions. This enables a compromised or malicious snap application, when running as root, to access sensitive system password hashes from the systemd-userdbd service, leading to information disclosure. This issue is mitigated on systems where the systemd-userdbd service is not installed by default.
