Description OSIDB Bzimport 2026-03-31 18:02:57 UTC 
Out-of-bounds write in the streaming decoder component in aws-c-event-stream before 0.6.0 might allow a third party operating a server to cause memory corruption leading to arbitrary code execution on a client application that processes crafted event-stream messages.

To remediate this issue, users should upgrade to version 0.6.0 or later.
