Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2025-32387)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote unauthenticated attacker can craft a JSON Schema file within a chart with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow.


2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-32386)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). A remote attacker can trick the victim into opening this specially crafted chart to cause memory exhaustion and the application to be terminated.
