Summary

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.

Risk Assessment

An attacker may cause memory corruption and potentially execute arbitrary code in the client application, risking full compromise of the process. The risk applies to applications processing untrusted event streams.

Recommendation

Upgrade aws-c-event-stream to version 0.6.0 or later. Limit processing of event streams from untrusted sources.
