However, libtar does not validate the file > names stored inside a tar file, possibly leading to a file extraction > outside the prefix path. For example, consider a file name > "../../etc/passwd". If extract_all is called with prefix "/home/USER/", > libtar would try to overwrite "/etc/passwd". not fixed yet: https://lists.feep.net:8080/pipermail/libtar/2013-October/000362.html > Once I figure out the right way of handling this, there will probably be > another libtar release.
