Path Traversal occurrences in File-roller
fr-archive-libarchive.c in GNOME file-roller through 3.36.1 allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink to a directory outside of the intended extraction location. (2020-04-13, CVE-2020-11736)
An issue was discovered in GNOME file-roller before 3.29.91. It allows a single ./../ path traversal via a filename contained in a TAR archive, possibly overwriting a file during extraction. (2019-09-21, CVE-2019-16680)
Why Path Traversal can be dangerous
Relative Path Confusion means that your web server is configured to serve responses to ambiguous URLs. This configuration can possibly cause confusion about the correct relative path for the URL. It is also an issue of resources, such as images, styles etc., which are specified in the response using relative path, not the absolute URL.
If the web browser permits to parse "cross-content" response, the attacker may be able to fool the web browser into interpreting HTML into other content types, which can then lead to a cross site scripting attack (link do XSS).
