"Two related issues have been discovered in Expat, a C library for
parsing XML.
- CVE-2012-6702
It was introduced when CVE-2012-0876 was addressed.
Stefan Sorensen discovered that the use of the function
XML_Parse() seeds the random number generator generating
repeated outputs for rand() calls.
- CVE-2016-5300
It is the product of an incomplete solution for
CVE-2012-0876. The parser poorly seeds the random number
generator allowing an attacker to cause a denial of
service (CPU consumption) via an XML file with crafted
identifiers.
You might need to manually restart programs and services using expat
libraries."
