Ipswitch IMail 5.0 LDAP Buffer Overflow DoS Vulnerability. Dos exploits for multiple platform
source: http://www.securityfocus.com/bid/503/info The IMail ldap service has an unchecked buffer, resulting in a classic buffer overflow vulnerability. While it does not crash the service, it drives CPU utilization up rendering the system essentially unusable. Telnet to target machine, port 389 Send: Y glob1 hit enter twice Server Returns: 0 Send: Y glob2 hit enter Where glob1 and glob2 are 2375 characters and Y is Y. The ldap service goes to 90 percent or so and idles there. Therefore using up most system resources.
