All the vulnerabilities related to the version 1.0.1 of the package
Arbitrary File Overwrite in fstream
Versions of fstream
prior to 1.0.12 are vulnerable to Arbitrary File Overwrite. Extracting tarballs containing a hardlink to a file that already exists in the system and a file that matches the hardlink will overwrite the system's file with the contents of the extracted file. The fstream.DirWriter()
function is vulnerable.
Upgrade to version 1.0.12 or later.
