Description:
 The xmlParseConditionalSections function in parser.c in libxml2 does not
 properly skip intermediary entities when it stops parsing invalid input,
 which allows context-dependent attackers to cause a denial of service
 (out-of-bounds read and crash) via crafted XML data, a different
 vulnerability than CVE-2015-7941.
