Description
Expat is a C library for parsing XML documents.
Security Fix(es):
- An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. (CVE-2016-0718)
