Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-202107-50 (Singularity: Remote code execution)

 Singularity always uses the default remote endpoint, ‘cloud.syslabs.io’, for action commands using the ‘library://’
 URI rather than the configured remote endpoint.
 Impact :

 An attacker that that can push a malicious container to the default remote endpoint could execute code on hosts that fetch the container.
 Workaround :

Solution

All Singularity users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=sys-cluster/singularity-3.7.4'
