HP OpenView NNM 0day, lightthpd DoS

An exploit has been published for HP OpenView Network Node Manager (NNM). This exploit is preauthentication and can be exploited remotely. From what I’ve read it looks to be exploited over the HTTP port of OpenView and is exploiting the OVAS.exe service. No references to updates or fixes were found. Users should restrict network access to machines running this software.

There’s a vulnerability in lightttpd that can be exploited to cause a denial of service. The issue exists in the SSL error queue where a single connection could be exploited to deny all other SSL connections. This has been fixed in the SVN repository, available at:
