The version of IBM HTTP Server running on the remote host is affected by multiple vulnerabilities related to Apache HTTP Server, as follows:
Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities.
(CVE-2012-1148)
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.
(CVE-2016-4472)
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. (CVE-2016-0718)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
