CWE-189  (opens in a new tab)

How to fix?

Upgrade unicode-org/icu to version 55.1 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 uses an integer data type that is inconsistent with a header file, which allows remote attackers to cause a denial of service (incorrect malloc followed by invalid free) or possibly execute arbitrary code via crafted text.
