Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Stack-based buffer overflow in the IAX2 channel driver (chan_iax2) in Asterisk before 1.2.22 and 1.4.x before 1.4.8, Business Edition before B.2.2.1, AsteriskNOW before beta7, Appliance Developer Kit before 0.5.0, and s800i before 1.0.2 allows remote attackers to execute arbitrary code by sending a long (1) voice or (2) video RTP frame.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

Upgrade to Asterisk 1.2.22+, 1.4.8+, Appliance Developer Kit 0.5.0+, s800i 1.0.2+, or AsteriskNOW beta7+

  1. 1. Identify the exact Asterisk product and version currently installed (e.g., 'asterisk -V' or check package manager)
  2. 2. For Asterisk 1.0.x versions: upgrade to Asterisk 1.2.22 or later, or ideally to the 1.4.x stable branch (1.4.8 or later)
  3. 3. For Asterisk 1.4.x versions: upgrade to Asterisk 1.4.8 or later, or migrate to a more recent stable branch like 1.6.x or 11.x
  4. 4. For AsteriskNOW beta_5/beta_6: upgrade to AsteriskNOW beta7 or later
  5. 5. For Asterisk Appliance Developer Kit <= 0.4: upgrade to version 0.5.0 or later
  6. 6. For S800i Appliance 1.0/1.0.1: upgrade to version 1.0.2 or later
  7. 7. After upgrading, restart the Asterisk service to apply changes
  8. 8. Verify the version after upgrade matches a fixed release
Caveat Upgrade between major branches (e.g., 1.0 to 1.4) may introduce configuration or dialplan syntax changes; test in non-production environment first
