    Package        : xerces-c
    CVE ID         : CVE-2016-4463
    Debian Bug     : 828990
    
    Brandon Perry discovered that xerces-c, a validating XML parser library
    for C++, fails to successfully parse a DTD that is deeply nested,
    causing a stack overflow. A remote unauthenticated attacker can take
    advantage of this flaw to cause a denial of service against applications
    using the xerces-c library.
    
    Additionally this update includes an enhancement to enable applications
    to fully disable DTD processing through the use of an environment
    variable (XERCES_DISABLE_DTD).
    
    For the stable distribution (jessie), this problem has been fixed in
    version 3.1.1-5.1+deb8u3.
    
    We recommend that you upgrade your xerces-c packages.
