Vulnerability Description
eopkg is a Solus package manager implemented in python3. In versions prior to 4.4.0, a malicious package could escape the directory set by `--destdir`. This requires the installation of a package from a malicious or compromised source.

Users only installing packages from the Solus repositories are not affected.
