libxml2: use-after-free in xmlUnlinkNode() in tree.c

Published Oct 6, 2023 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
Description
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."
