FreeBSD : ruby -- DoS vulnerability in REXML (844cf3f5-9259-4b3e-ac9e-13ca17333ed7)

High Nessus Plugin ID 64874


The remote FreeBSD host is missing a security-related update.


Ruby developers report :

Unrestricted entity expansion can lead to a DoS vulnerability in REXML. (The CVE identifier will be assigned later.) We strongly recommend to upgrade ruby.

When reading text nodes from an XML document, the REXML parser can be coerced in to allocating extremely large string objects which can consume all of the memory on a machine, causing a denial of service.


Update the affected package.
