Description

All versions of lix are vulnerable to Machine-In-The-Middle. The package accepts downloads with http and follows location header redirects for package downloads. This allows for an attacker in a privileged network position to intercept a lix package installation and redirect the download to a malicious source.

Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.

NVD description

lix through 15.8.7 allows man-in-the-middle attackers to execute arbitrary code by modifying the HTTP client-server data stream so that the Location header is associated with attacker-controlled executable content in the postDownload field.
