Description
pyLoad is a free and open-source download manager written in Python. Versions before 0.5.0b3.dev97 are vulnerable to path traversal during password verification of certain encrypted 7z archives (encrypted files with non-encrypted headers), causing arbitrary file deletion outside of the extraction directory. During password verification, pyLoad derives an archive entry name from 7z listing output and treats it as a filesystem path without constraining it to the extraction directory. This issue has been fixed in version 0.5.0b3.dev97.
