Cisco Systems Inc. almost made it through this year’s Black Hat Inc. security conference without a major controversy, scandal or problem. German researcher Hendrik Scholz of Freenet GmbH briefly mentioned a security flaw related to Cisco’s PIX firewalls. A Cisco spokesman says the company has just begun investigating the validity and scope of the flaw. It’s not clear whether the PIX flaw he mentioned was directly related to SIP or to VOIP security. Cisco has handed the problem to its Product Security Incident Response Team.”]
