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. Files in such packages would not be installed in the path given by `--destdir`, but on a different location on the host. The issue has been fixed in v4.4.0. Users only installing packages from the Solus repositories are not affected.

Analysis

Eopkg package manager versions before 4.4.0 fail to enforce the --destdir installation path, allowing malicious packages to write files to arbitrary locations on the host filesystem. An attacker can exploit this by distributing a compromised package that bypasses the intended installation directory, potentially overwriting system files or placing malicious content outside the sandboxed installation path. …
