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.

### Impact Systems that run `distribution` built after a specific commit running on memory-restricted environments can suffer from denial of service by a crafted malicious `/v2/_catalog` API endpoint request. ### Patches Upgrade to at least 2.8.2-beta.1 if you are running `v2.8.x` release. If you use the code from the main branch, update at least to the commit after [f55a6552b006a381d9167e328808565dd2bf77dc](https://github.com/distribution/distribution/commit/f55a6552b006a381d9167e328808565dd2bf77dc). ### Workarounds There is no way to work around this issue without patching. Restrict access to the affected API endpoint: see the recommendations section. ### References `/v2/_catalog` endpoint accepts a parameter to control the maximum amount of records returned (query string: `n`). When not given the default `n=100` is used. The server trusts that `n` has an acceptable value, however when using a maliciously large value, it allocates an array/slice of `n` of strings before fi...
