OVERVIEW:

       Avaya have released three advisories relating to vulnerabilities in
       libxml2 [1], ipsec-tools [2], and bzip2 [3], and how they affect 
       their products.


IMPACT:

       Exploitation of these vulnerabilities may result in a Denial of 
       Service (DoS).
 

MITIGATION:

       Users of the affected products should restrict access to the
       server until a patch is released.

       Products that run on general purpose operating systems (ie those
       that are 'software only') should upgrade the relevant package on
       the underlying operating system.
