# Which issue does this PR close? No issue filed. # Rationale for this change We allocate memory based on metadata length - If an untrusted client writes a meta len of < 0 then we'll allocate a large number of bytes due to sign extension and likely panic. # What changes are included in this PR? - Update StreamReader in both places it reads metadata length for < 0 which is at the start of the stream to read the schema, and in the middle of the stream between each message. # Are these changes tested? Yes, tests for both reads are added # Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
