It was discovered that file before 5.17 contains a flaw in the handling of "indirect" magic rules in the libmagic library, which leads to an infinite recursion when trying to determine the file type of certain files (CVE-2014-1943).
Additionally, other well-crafted files might result in long computation times (while using 100% CPU) and overlong results.
The affected packages have been patched to correct these flaws.
