The remote NewStart CGSL host, running version MAIN 6.02, has libxml2 packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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)

  - 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)

  - A NULL pointer dereference vulnerability was found in libxml2. This issue occurs when parsing (invalid)     XML schemas. (CVE-2023-28484)

  - 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)
