Amazon Linux 2 : flatpak (ALAS-2021-1625)

high Nessus Plugin ID 148337

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of flatpak installed on the remote host is prior to 1.0.9-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1625 advisory.

 A sandbox escape flaw was found in the way flatpak handled special tokens in .desktop files. This flaw allows an attacker to gain access to files that are not ordinarily allowed by the app's permissions. The highest threat from this vulnerability is to confidentiality and integrity. (CVE-2021-21381)

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 'yum update flatpak' to update your system.
