        Rhodri James discovered an infinite loop vulnerability within the
        entityValueInitProcessor() function while parsing malformed XML
        in an external entity. An attacker can take advantage of this
        flaw to cause a denial of service against an application using
        the Expat library.
    
    For the oldstable distribution (jessie), these problems have been fixed
    in version 2.1.0-6+deb8u4.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 2.2.0-2+deb9u1. For the stable distribution (stretch),
    CVE-2016-9063 was already fixed before the initial release.
    
    For the testing distribution (buster), these problems have been fixed
    in version 2.2.1-1 or earlier version.
    
    For the unstable distribution (sid), these problems have been fixed in
