libxml has a memory access bug that has the potential of being exploited. Good to fix.
Libxml have multiple vulns. From my perspective can be autgened but is main part of Gnome but i not use this Env. And I would not like to contribute to destabilization.
It's nice, however, if this package was autogeneroeany, while someone more experienced in Gnome thinks that he will be a better tester than me

"is_known_exploited_vuln": false,
"description": "There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.",

"id": "CVE-2022-2309",
"is_known_exploited_vuln": false,
"description": "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.",
