Security Fix(es):
libxml2: 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.(CVE-2022-40303)
libxml2: A flaw was found in libxml2. When a reference cycle is detected in the XML entity cleanup function the XML entity data can be stored in a dictionary. In this case, the dictionary becomes corrupted resulting in logic errors, including memory errors like double free.(CVE-2022-40304)
libxml2: A Cross-site scripting (XSS) vulnerability was found in libxml2. A specially crafted input, when serialized and re-parsed by the libxml2 library, will result in a document with element attributes that did not exist in the original document.(CVE-2016-3709)
libxml2: A flaw was found in libxml2. This issue occurs when hashing empty strings which aren't null-terminated, xmlDictComputeFastKey could produce inconsistent results, which may lead to various logic or memory errors, including double free errors.(CVE-2023-29469)
