Multiple vulnerabilities have been identified in HP OpenView Network Node Manager (NNM), which could be exploited by remote attackers to cause a denial of service or compromise a vulnerable system. These issues are caused by buffer overflow errors in the "OpenView5.exe", "getcvdata.exe", "ovlaunch.exe", and "Toolbar.exe" CGI applications when processing overly long parameter strings, which could allow attackers to crash an affected application or execute arbitrary code via a specially crafted HTTP request.
