Beschreibung:	Summary: The remote host is missing an update for the 'libxml2' package(s) announced via the MGASA-2023-0157 advisory. Vulnerability Insight: NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered. (CVE-2022-2309) NULL dereference in xmlSchemaFixupComplexType. (CVE-2023-28484) Hashing of empty dict strings isn't deterministic. (CVE-2023-29469) Affected Software/OS: 'libxml2' package(s) on Mageia 8. Solution: Please install the updated package(s).
