AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an uncontrolled recursion flaw in the libxml2 XML parsing library, specifically in the xmlCatalogXMLResolveURI function. When an XML catalog contains a delegate URI entry that references itself, the function recursively tries to resolve the same catalog entry repeatedly without detecting the cycle. This causes infinite recursion, exhausting the call stack and resulting in a segmentation fault that crashes the application. [1]
How can this vulnerability impact me? :
This vulnerability can be exploited by a remote attacker who provides a specially crafted XML catalog that triggers infinite recursion. The impact is a Denial of Service (DoS) by crashing applications that use libxml2 for XML parsing, leading to unavailability of affected services or software. [1]
