    Package : expat
    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

    It 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

    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.

    For the stable distribution (jessie), these problems have been fixed in
    version 2.1.0-6+deb8u3.

    For the unstable distribution (sid), these problems have been fixed in
    version 2.1.1-3.

    We recommend that you upgrade your expat packages.
