     recovery mode, allowed context-dependent attackers to cause a denial of
     service (infinite recursion, stack consumption, and application crash)
     via a crafted XML document (bsc#972335).
   - CVE-2016-1833: libxml2 allowed remote attackers to execute arbitrary
     code or cause a denial of service (memory corruption) via a crafted XML
     document, a different vulnerability than CVE-2016-1834, CVE-2016-1836,
     CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840

   - CVE-2016-1837: libxml2 allowed remote attackers to execute arbitrary
     code or cause a denial of service (memory corruption) via a crafted XML
     document, a different vulnerability than CVE-2016-1833, CVE-2016-1834,
     CVE-2016-1836, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840
     (bsc#981111).
   - CVE-2016-1836: libxml2 allowed remote attackers to execute arbitrary
     code or cause a denial of service (memory corruption) via a crafted XML
     document, a different vulnerability than CVE-2016-1833, CVE-2016-1834,
     CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840
     (bsc#981110).
   - CVE-2016-1839: libxml2 allowed remote attackers to execute arbitrary
     code or cause a denial of service (memory corruption) via a crafted XML
     document, a different vulnerability than CVE-2016-1833, CVE-2016-1834,
     CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, and CVE-2016-1840

     (bsc#981112).
   - CVE-2016-1840: libxml2 allowed remote attackers to execute arbitrary

     (bsc#981041).
   - CVE-2016-3705: The (1) xmlParserEntityCheck and (2)
     xmlParseAttValueComplex functions in parser.c in libxml2 did not
     properly keep track of the recursion depth, which allowed
     context-dependent attackers to cause a denial of service (stack
     consumption and application crash) via a crafted XML document containing
     a large number of nested entity references (bsc#975947).
   - CVE-2016-1762: libxml2 allowed remote attackers to execute arbitrary
     code or cause a denial of service (memory corruption) via a crafted XML
     document (bsc#981040).
