What is CVE-2007-4280?

The Skinny channel driver (chan_skinny) in various versions of Asterisk Open Source and its appliances allows authenticated remote users to trigger a denial of service. This occurs by sending a specially crafted CAPABILITIES_RES_MESSAGE packet that exceeds the allocated capabilities_res_message array, resulting in an application crash. Administrators should ensure that their Asterisk systems are updated to the latest versions to mitigate this vulnerability.
