GHSA-84mq-mqjx-rfmc PUBLISHED CVSS 9.800000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 14, 2022

The ucnv_UTF8FromUTF8 function in ucnv_u8.cpp in International Components for Unicode (ICU) for C/C++ through 60.1 mishandles ucnv_convertEx calls for UTF-8 to UTF-8 conversion, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted string, as demonstrated by ZNC.
