Description OSIDB Bzimport 2026-06-12 19:01:52 UTC 
Improper handling of HPACK dynamic table size updates in the AWS Common Runtime aws-c-http library might allow a remote threat actor operating a server to cause memory corruption on a connecting client application, potentially leading to arbitrary code execution, via a crafted sequence of HTTP/2 HEADERS frames.



To remediate this issue, users should upgrade to aws-c-http version 0.11.0.
