CVE-2011-2560

Name of the Vulnerable Software and Affected Versions Cisco Unified Communications Manager versions 4.x

Description The issue is related to the Packet Capture Service in Cisco Unified Communications Manager, which does not properly handle idle TCP connections. This allows remote attackers to cause a denial of service by making many connections, resulting in memory consumption and restart.
