Alex Murray discovered a stack-based buffer overflow vulnerability in fribidi, an implementation of the Unicode Bidirectional Algorithm algorithm, which could result in denial of service or potentially the execution of arbitrary code, when processing a large number of unicode isolate directional characters.
