Background
The ICU (International Components for Unicode) package is a widely used library that provides robust and full-featured Unicode and Globalization support for software applications. It is essential for handling text in multiple languages and formats, ensuring that applications can operate seamlessly across different locales. However, like any software, ICU is susceptible to vulnerabilities that can compromise its integrity and the security of applications that rely on it.

Workaround
As a temporary workaround, users may consider limiting the input data processed by the ICU library or implementing additional validation checks on the data before it is passed to ICU functions. However, these measures do not replace the need for an update and should only be used until the patch is applied.
