FriBidi Python binding (pyfribidi) Heap Buffer Overflow Vulnerability

FriBidi Python binding (pyfribidi) is prone to a heap-based buffer-overflow vulnerability because the application fails to perform adequate boundary-checks on user-supplied data.

An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts may result in a denial-of-service condition.

NOTE: pyfribidi is affected only if Fribidi 0.19.1 or later is installed.
