Abstract:  CVE-2015-1283 for IBM HTTP Server

Description/symptom of problem:  
PI45596 resolves the following problem:

ERROR DESCRIPTION:
Potential denial of service due to vulnerability in Expat 
bundled with IBM HTTP Server.                            

LOCAL FIX:                                                      

PROBLEM SUMMARY:
Multiple integer overflows in Expat (bundled with IBM HTTP 
Server), can potentially allow remote attackers to cause a 
denial of service (heap-based buffer overflow), or possibly 
have an unspecified other impact via crafted XML data.                                          

PROBLEM CONCLUSION:
The bundled expat in IBM HTTP Server was updated.
