Any SpiceDB cluster with any schema where a resource being checked has more than 65535 relationships for the same resource and subject type is affected by this problem. The issue may also lead to a panic rendering the server unavailable The following API methods are affected: - [CheckPermission](https://buf.build/authzed/api/docs/main:authzed.api.v1#authzed.api.v1.PermissionsService.CheckPermission) - [BulkCheckPermission](https://buf.build/authzed/api/docs/main:authzed.api.v1#authzed.api.v1.ExperimentalService.BulkCheckPermission) - [LookupSubjects](https://buf.build/authzed/api/docs/main:authzed.api.v1#authzed.api.v1.PermissionsService.LookupSubjects) #### Impact Permission checks that are expected to be allowed are instead denied, and lookup subjects will return fewer subjects than expected. #### Workarounds There is no workaround other than making sure that the SpiceDB cluster does not have very wide relations, with the maximum value being the maximum value of an 16-bit unsig...
## Preconditions - The `code` login method is enabled with the `passwordless_enabled` flag set to `true` . - A 2FA method such as `totp` is enabled. - `required_aal` of the whomai check or the settings flow is set to `highest_available`. AAL stands for Authenticator Assurance Levels and can range from 0 (no factor) to 2 (two factors). - A user uses the `code` method as the **only** login method available. They do not have a password or any other first factor credential enabled. - The user has 2FA enabled. - The user’s `available_aal` is incorrectly stored in the database as `aal1` or `aal0` or `NULL`. - A user signs in using the code method, but does not complete the 2FA challenge. **Example server configuration** Below you will find an vulnerable example configuration. Keep in mind that, for the account to be vulnerable, the account must have no first factor except the `code` method enabled plus a second factor. ``` selfservice: methods: code: # The `code` login method...
KrebsOnSecurity celebrates its 14th year of existence today! I promised myself this post wouldn't devolve into yet another Cybersecurity Year in Review. Nor do I wish to hold forth about whatever cyber horrors may await us in 2024.

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, Grappler component of TensorFlow is vulnerable to an integer overflow during cost estimation for crop and resize. Since the cropping parameters are user controlled, a malicious person can trigger undefined behavior. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
