A flaw was found in the `/v2/_catalog` endpoint in distribution/distribution which accepts a parameter to control the maximum number of records returned (query string: `n`). This vulnerability allows a malicious user to submit an unreasonably large value for `n` causing the allocation of a massive string array possibly causing a denial of service through excessive use of memory.
