Описание
A flaw was found in libxml2. 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.
Отчет
Per upstream:
It's NOT recommended to use this software to process untrusted data. There is a lot of ways that a malicious crafted xml could exploit a hidden vulnerability in the software.
