EulerOS 2.0 SP5 : polkit (EulerOS-SA-2019-2223)

high Nessus Plugin ID 130685

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the polkit packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A flaw was found in polkit before version 0.116. The implementation of the polkit_backend_interactive_authority_check_authorizatio n function in polkitd allows to test for authentication and trigger authentication of unrelated processes owned by other users. This may result in a local DoS and information disclosure.(CVE-2018-1116)

- 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.(CVE-2015-3255)

- 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.(CVE-2015-3218)

- A flaw was found in PolicyKit (aka polkit) 0.115 that allows a user with a uid greater than INT_MAX to successfully execute any systemctl command.(CVE-2018-19788)

- 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.(CVE-2015-4625)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected polkit packages.
