libarchive.so is vulnerable to File Permission Bypass. The vulnerability exists due to a race condition in _archive_write_disk_header
function at archive_write_disk_posix.c
because the unmasking process does not take intro consideration other threads working on the same file, which allows an attacker to delete and rename files inside the directories.
