    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.
