| Doc Text: |
A flaw was found in the msgpack decoder. A remote attacker could send specially crafted, truncated fixext data to an application using the msgpack library. This improper input validation can lead to an out-of-bounds read and a runtime panic, resulting in a denial of service (DoS) attack against the application.
