Уязвимость реализации функции wrap_nettle_hash_fast() криптографической библиотеки GnuTLS, позволяющая нарушителю вызвать отказ в обслуживании

A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances.

Уязвимость платформы для мониторинга и наблюдения Grafana, связанная с разрешительный список разрешенных входов, позволяющая нарушителю повысить свои привилегии

Уязвимость платформы для мониторинга и наблюдения Grafana, связанная с недостатками списка контроля доступом (ACL), позволяющая нарушителю обойти существующие ограничения доступа

Grafana is an open-source platform for monitoring and observability. 

In Grafana Enterprise, Request security is a deny list that allows admins to configure Grafana in a way so that the instance doesn’t call specific hosts.

However, the restriction can be bypassed used punycode encoding of the characters in the request address.

Grafana is an open-source platform for monitoring and observability. The vulnerability impacts Grafana instances with several organizations, and allows a user with Organization Admin permissions in one organization to change the permissions associated with Organization Viewer, Organization Editor and Organization Admin roles in all organizations.

It also allows an Organization Admin to assign or revoke any permissions that they have to any user globally.

This means that any Organization Admin can elevate their own permissions in any organization that they are already a member of, or elevate or restrict the permissions of any other user.

The vulnerability does not allow a user to become a member of an organization that they are not already a member of, or to add any other users to an organization that the current user is not a member of.
