Description:
 libxml2 2.9.2 does not properly stop parsing invalid input, which allows
 context-dependent attackers to cause a denial of service (out-of-bounds
 read and libxml2 crash) via crafted XML data to the (1) xmlParseEntityDecl
 or (2) xmlParseConditionalSections function in parser.c, as demonstrated by
 non-terminated entities.
