    other files may not be opened, which made it easier for
    remote attackers to conduct XML External Entity (XXE)

  - Prevent NULL dereference in xpointer.c and

    earlier and other products, does not offer a flag
    directly indicating that the current document may be
    read but other files may not be opened, which makes it
    easier for remote attackers to conduct XML External
    Entity (XXE) attacks via a crafted

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
