The issue allows context-dependent attackers to cause a denial of service, resulting in an out-of-bounds read and crash, via crafted UTF-8 data. This is due to a problem in the

For versions prior to 1.33, update to version 1.33 or later to resolve the issue. As a temporary workaround, consider restricting the input of crafted UTF-8 data to the
stringprep utf8 nfkc normalize function until a patch is available.Correção
