Package : expat
Version : 2.1.0-1+deb7u4
CVE ID : CVE-2012-6702 CVE-2016-5300
Two related issues have been discovered in Expat, a C library for
parsing XML.
CVE-2012-6702
This issue was introduced when CVE-2012-0876 was addressed. Stefan
Sørensen discovered that the use of the function XML_Parse() seeds
the random number generator generating repeated outputs for rand()
calls.
CVE-2016-5300
This 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.
For Debian 7 "Wheezy", these problems have been fixed in version
2.1.0-1+deb7u4.
We recommend that you upgrade your expat packages.
