-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of HP 3com/H3C Intelligent Management Center.
Authentication is not required to exploit this vulnerability.

The flaw exists within the imcsyslogdm.exe component which listens by
default on UDP port 514. When handling a syslog packet having a size
larger than 2048 bytes the process attempts to exit. An exception
handler is called that makes a call into a location that has been
previously freed. A remote attacker can exploit this vulnerability to
execute arbitrary code under the context of the SYSTEM user.
