CVE-2008-3281
libxml2 2.6.32 and earlier does not properly detect recursion during
entity expansion in an attribute value, which allows context-dependent
attackers to cause a denial of service (memory and CPU consumption)
via a crafted XML document.

CVE-2008-3529
Heap-based buffer overflow in the xmlParseAttValueComplex function in
parser.c in libxml2 before 2.7.0 allows context-dependent attackers to
cause a denial of service (crash) or possibly execute arbitrary code
via a long XML entity name.";
