CVE-2022-23308

A flaw was found in libxml2. A call to the xmlGetID function can return a pointer already freed when parsing an XML document with the XML_PARSE_DTDVALID option and without the XML_PARSE_NOENT option, resulting in a use-after-free issue.

The security impact of xmlGetID() returning a pointer to freed memory depends on the application and will mostly result in a denial of service (DoS). The typical use case of calling xmlGetID() on an unmodified document is not affected, therefore this issue was rated with a moderate severity.
