I've just installed CMF 22.214.171.124 in addition to Comodo Firewall and Avira Antivir on Vista 64-bit, which is also a fresh install - I'm doubtful of infections, especially as none have been actually detected and CFP doesn't inform about any abnormalities.
Anyhow I'm getting constant alerts from CMF about ret2libc type attacks and most seem to occur with Windows system applications, but some also with console programs. Something I find peculiar is that the memory address is always the same.
Are there any known non-threatening conditions that can cause these alarms or a known bug? Or should I file a bug report?
Here's a screenshot of CMF's log window:
