SYNTHESIS OF THE VULNERABILITY
An attacker can create a memory leak by opening a large number of
TCP connections to Cisco Unified Communications Manager IM and
Presence Service, in order to trigger a denial of service.
Impacted products: Cisco CUCM
Severity: 2/4
Creation date: 21/08/2013
DESCRIPTION OF THE VULNERABILITY
The Cisco Unified Communications Manager IM and Presence Service
product listens on ports 5060/tcp or 5061/tcp.
A memory area is allocated for each connection. However, it is
never freed.
An attacker can therefore create a memory leak by opening a large
number of TCP connections to Cisco Unified Communications Manager
IM and Presence Service, in order to trigger a denial of service.
