This indicates an attempted exploit of a buffer-overflow vulnerability in various Computer Associates products.
These can be exploited by remote users to execute arbitrary code on an affected machine or to trigger denial-of-service conditions. This is due to the application's failure to properly handle an overly long parameter passed to the log_security() function (on port 4105/tcp), which could be exploited by remote attackers to execute arbitrary commands and compromise a vulnerable system.
