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&#39;s position is "I don&#39;t think these issues are critical enough to warrant a CVE ID ... because an attacker typically can&#39;t control when memory allocations fail."
