Summary

The streaming decoder component in aws-c-event-stream before version 0.6.0 has an out-of-bounds write. A server sending crafted event-stream messages can cause memory corruption and potentially remote code execution in the client application.

Risk Assessment

An attacker controlling the server can take over the client application processing event-stream messages, leading to full client compromise.

Recommendation

Upgrade the aws-c-event-stream library to version 0.6.0 or later.

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.
