CVE-2024-1724 – snapd allows $HOME/bin symlink

https://notcve.org/view.php?id=CVE-2024-1724

In snapd versions prior to 2.62, when using AppArmor for enforcement of sandbox permissions, snapd failed to restrict writes to the $HOME/bin path. In Ubuntu, when this path exists, it is automatically added to the users PATH. An attacker who could convince a user to install a malicious snap which used the 'home' plug could use this vulnerability to install arbitrary scripts into the users PATH which may then be run by the user outside of the expected snap sandbox and hence allow them to escape confinement. • https://github.com/snapcore/snapd/commit/aa191f97713de8dc3ce3ac818539f0b976eb8ef6 https://github.com/snapcore/snapd/pull/13689 https://gld.mcphail.uk/posts/explaining-cve-2024-1724 • CWE-732: Incorrect Permission Assignment for Critical Resource •
