CVE-2022-40303

A flaw was found in libxml2. Parsing a XML document with the XML_PARSE_HUGE option enabled can result in an integer overflow because safety checks were missing in some functions. Also, the xmlParseEntityValue function didn't have any length limitation.

This flaw is only triggered when parsing a multi-gigabyte XML document with the XML_PARSE_HUGE option enabled, and the most likely impact of this flaw is a Denial of Service in the application linked to the library. To reflect these conditions, Red Hat Product Security has rated this flaw as having a moderate security impact.
