Total Amount Of Asterisk Installations


Counting any Open Source package is difficult for many reasons. There is probably not a reliable answer to this question since there are at least 4 major “flavors” of Asterisk out there (1.4, 1.6, 1.8, 1.10) and open and commercial source. It is reliably > 10,000 and quite possibly over 100,000 or even over 1 million. The Asterisk folks might be willing to tell you how many downloads have been done from , but that wouldn’t tell you the real number. Maybe a good start point for an estimate would start at 200,000+ if you are including all of the versions and types. But then we might still think…

Heap Buffer Overflow in Skinny Channel Driver


In the Skinny channel driver, KEYPAD_BUTTON_MESSAGE events are queued for processing in a buffer allocated on the heap, where each DTMF value that is received is placed on the end of the buffer. Since the length of the buffer is never checked, an attacker could send sufficient KEYPAD_BUTTON_MESSAGE events such that the buffer is overrun. Now, the length of the buffer is now checked before appending a value to the end of the buffer. Affected Versions:

  • Product Release Series
  • Asterisk Open Source 1.6.2.x All Versions
  • Asterisk Open Source 1.8.x All Versions
  • Asterisk Open Source 10.x All Versions
