Description

A flaw was found in expat. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by submitting a large XML document to an application that reuses parser instances. When the XML parser is reset using XML_ParserReset, it clears the direct byte count but fails to offset tracked heap allocations. Consequently, subsequent parsing operations on the reused parser fail with out-of-memory errors until the parser is completely recreated.
