Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
uriparser:
* mingw32-uriparser-1.0.1-1.hum1 (noarch)
* mingw64-uriparser-1.0.1-1.hum1 (noarch)
* uriparser-1.0.1-1.hum1 (aarch64, x86_64)
* uriparser-devel-1.0.1-1.hum1 (aarch64, x86_64)

A flaw was found in uriparser. This vulnerability occurs due to numeric truncation in text range comparison when an application processes extremely long Uniform Resource Identifiers (URIs), specifically those with lengths in gigabytes. A local attacker could exploit this flaw by providing a malformed, excessively long URI, leading to a Denial of Service (DoS) condition where the application becomes unavailable.
