Vulnerability Details
CVE-ID: CVE-2016-2073
Description: libxml2 is vulnerable to a heap-based buffer overflow, caused by
an out-of-bounds read in the htmlParseNameComplex() function. By persuading a
victim to open a specially crafted XML file, a remote attacker could overflow
a buffer and execute arbitrary code on the system or cause the application to
crash.

CVE-ID: CVE-2016-9318
Description: Libxml2 could allow a remote attacker to obtain sensitive
information, caused by failure to offer a flag directly indicating the status
of current document. By using a specially-crafted document to conduct a XML
external entity (XXE) attack, an attacker could exploit this vulnerability to
obtain sensitive information.
