Name of the Vulnerable Software and Affected Versions APM Server (affected versions not specified)
Description Improper handling of highly compressed data in APM Server can lead to a persistent denial of service through excessive allocation. An authenticated user with write access to source map content can store specially crafted, highly compressed content. When this content is processed, it exhausts the available memory, causing the process to terminate. This condition persists and recurs upon every restart until the stored content is removed.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
