-Description: fix multiple integer overflows in the XML_GetBuffer function
- Multiple integer overflows in the XML_GetBuffer function in Expat through
- 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products,
- allow remote attackers to cause a denial of service (heap-based buffer
- overflow) or possibly have unspecified other impact via crafted XML data,
- a related issue to CVE-2015-2716.
