The remote Fedora host is missing one or more security updates.
Add a patch to fix a problem with the manager interface. Update to 18.104.22.168 to fix AST-2009-001 / CVE-2009-0041: http://downloads.digium.com/pub/security/AST-2009-001.html (Original patch in 22.214.171.124 introduced a regression.) Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Update the affected asterisk, dahdi-tools and / or libresample packages.
