affected by a denial of service vulnerability.");

"According to its self-reported version number, the version of
Atlassian JIRA hosted on the remote web server is prior to 5.0.1. It
is, therefore, potentially affected by an XML parsing flaw due to
improper restrictions on the capabilities of third-party parsers. A
remote, authenticated attacker can exploit this to perform a denial of
service attack against JIRA.

The Tempo and Gliffy plugins for JIRA are also affected by this
vulnerability; however, Nessus did not confirm that these plugins are
installed. If you are using these plugins with any version of JIRA,
you should upgrade or disable them.

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
