Amazon Linux 2023 : bubblewrap (ALAS2023-2024-726)

critical Nessus Plugin ID 208975

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-726 advisory.

A sandbox escape vulnerability was found in Flatpak due to a symlink-following issue when mounting persistent directories. This flaw allows a local user or attacker to craft a symbolic link that can bypass the intended restrictions, enabling access to and modification of files outside the designated sandbox. As a result, the attacker could potentially manipulate the file system, leading to unauthorized actions that compromise the security and integrity of the system.

Flatpak is not providing a security boundary that protects the OS from untrusted content in the flatpak.
Flatpak applications should be vetted and reviewed with the same attention as regular OS packages. It should be assumed that an installed flatpak shares the same privileges and access than the user running it. (CVE-2024-42472)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update bubblewrap --releasever 2023.6.20241010' to update your system.
