"According to the version of the librepo packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :
- A flaw was found in librepo in versions before 1.12.1.
A directory traversal vulnerability was found where it
failed to sanitize paths in remote repository metadata.
An attacker controlling a remote repository may be able
to copy files outside of the destination directory on
the targeted system via path traversal. This flaw could
potentially result in system compromise via the
overwriting of critical system files. The highest
threat from this flaw is to users that make use of
untrusted third-party repositories.(CVE-2020-14352)
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
