Name of the Vulnerable Software and Affected Versions PyFriBidi versions prior to 0.11.0

Description The issue is related to a buffer overflow in the fribidi utf8 to unicode function, which can be exploited by remote attackers to cause a denial of service, resulting in an application crash. This can be achieved by sending a specifically crafted 4-byte UTF-8 sequence.

Recommendations For versions prior to 0.11.0, update to version 0.11.0 or later to resolve the issue. As a temporary workaround, consider restricting input to prevent the processing of malicious UTF-8 sequences until a patch is applied.
