Summary
libxmltok vulnerabilities
Details

Shang-Hung Wan discovered that Expat, contained within the xmltok library, did not properly handle certain function calls when a negative input length was provided. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2024-45490)
