This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable.\n\n## Affected\n\n- `libxml2 >= 2.13.0, < 2.15.3`\n- `hardened_images`\n- `jboss_core_services`\n- `openshift_container_platform = 4.0`\n- `enterprise_linux = 6.0`\n- `enterprise_linux = 7.0`\n- `enterprise_linux = 8.0`\n- `enterprise_linux = 9.0`\n- `enterprise_linux = 10.0`\n- `vios >= 4.1.0, < 4.1.1.30`\n- `vios = 4.1.2.0`\n- `aix >= 7.2.5, < 7.2.5.12`\n- `aix >= 7.3.2, < 7.3.3.3`\n- `aix = 7.3.4`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `libxml2 2.15.3`\n- `vios 4.1.1.30`\n- `aix 7.3.3.3`","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
