Lifecycle Timeline
3DescriptionGitHub Advisory
eopkg is a Solus package manager implemented in python3. In versions prior to 4.4.0, a malicious package could include files that are not tracked by eopkg. This requires the installation of a package from a malicious or compromised source. Files in such packages would not be shown by lseopkg and related tools. The issue has been fixed in v4.4.0. Users only installing packages from the Solus repositories are not affected.
AnalysisAI
Eopkg package manager versions before 4.4.0 fail to track files included in malicious packages, allowing undetected file installation when users install from compromised sources. An attacker can distribute packages containing hidden files that evade detection by package management tools like lseopkg. Users installing exclusively from official Solus repositories are unaffected.
