What is CVE-2018-10184?

A vulnerability exists in HAProxy prior to version 1.8.8 due to a misconfiguration in how incoming H2 frame lengths are validated. This issue allows for the possibility of heap overflow when a large frame size is advertised. If exploited, this can lead to service crashes, although the likelihood of executing arbitrary code is low. It is essential for users to upgrade to the latest version to mitigate these risks.
