Name of the Vulnerable Software and Affected Versions:
Apache APR-util versions prior to 1.3.7
Apache HTTP Server (affected versions not specified)
Description:
The issue allows remote attackers to cause a denial of service due to excessive memory consumption. This can be achieved by sending a crafted XML document containing a large number of nested entity references. For example, this could be demonstrated by a PROPFIND request. The problem is related to the expat XML parser in the apr xml * interface.
Recommendations:
For Apache APR-util versions prior to 1.3.7, update to version 1.3.7 or later to resolve the issue.
For the Apache HTTP Server, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
