EulerOS Virtualization for ARM 64 3.0.1.0 : sssd (EulerOS-SA-2019-1411)

high Nessus Plugin ID 124914

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the sssd packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD utilizes too broad of a set of permissions. Any user who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user.(CVE-2018-10852)

 - It was found that sssd's sysdb_search_user_by_upn_res() function did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.(CVE-2017-12173)

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 sssd packages.
