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.
