coreutils: GNU coreutils uniq: Denial of Service and information disclosure via out-of-bounds read with multibyte input

A flaw was found in GNU coreutils uniq. When processing specially crafted multibyte input with the --check-chars option, an attacker can trigger an out-of-bounds read. This vulnerability can lead to a denial of service DoS due to an application crash and potentially expose sensitive information...
