Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

A memory buffer overflow vulnerability exists in the internal diagnostic and route validation routines used by the Fabric Shortest Path First (FSPF) protocol component of Brocade Fabric OS versions before 10.0.1. While this code path is part of internal diagnostic functionality and is not directly accessible via standard user interfaces or CLI management commands, an input processing flaw allows incoming or internally routed diagnostic state payloads to exceed allocated memory boundaries. An attacker that is able to chain or link other vulnerabilities to exploit this internal diagnostic could cause a heap- or stack-based memory overrun, resulting in a daemon crash (Denial of Service) or potential arbitrary code execution within the context of the routing daemon.
