### 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...

Ubuntu Security Notice 6072-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6071-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6070-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
