Colin Walters reports :

  • Integer overflow in the authentication_agent_new_cookie function in PolicyKit (aka polkit) before 0.113 allows local users to gain privileges by creating a large number of connections, which triggers the issuance of a duplicate cookie value.

  • The authentication_agent_new function in polkitbackend/polkitbackendinteractiveauthority.c in PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (NULL pointer dereference and polkitd daemon crash) by calling RegisterAuthenticationAgent with an invalid object path.

  • The polkit_backend_action_pool_init function in polkitbackend/polkitbackendactionpool.c in PolicyKit (aka polkit) before 0.113 might allow local users to gain privileges via duplicate action IDs in action descriptions.

  • PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (memory corruption and polkitd daemon crash) and possibly gain privileges via unspecified vectors, related to ‘javascript rule evaluation.’
