A vulnerability was found in libarchive. This issue can cause a race condition in a multi-threaded use of archive_write_disk_header() on posix based systems, which could allow implicit directory creation with permissions 777, without sticky bit, which means any low privileged user on the system can delete and rename files inside those directories.
