The remote host is affected by the vulnerability described in GLSA-202402-11 (libxml2: Multiple Vulnerabilities)

  - In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference     and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c. (CVE-2023-28484)

  - An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML     document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic     and memory errors, such as a double free. This behavior occurs because there is an attempt to use the     first byte of an empty string, and any value is possible (not solely the '\0' value). (CVE-2023-29469)

  - libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails.
    This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is I don't think these issues are     critical enough to warrant a CVE ID ... because an attacker typically can't control when memory     allocations fail. (CVE-2023-45322)

  - An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5. When using the XML Reader     interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to     an xmlValidatePopElement use-after-free. (CVE-2024-25062)
