NewStart CGSL CORE 5.04 / MAIN 5.04 : sssd Multiple Vulnerabilities (NS-SA-2019-0195)

medium Nessus Plugin ID 129890

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has sssd packages installed that are affected by multiple vulnerabilities:

 - A vulnerability was found in sssd. If a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot() etc. All versions before 2.1 are vulnerable. (CVE-2019-3811)

 - A flaw was found in sssd Group Policy Objects implementation. When the GPO is not readable by SSSD due to a too strict permission settings on the server side, SSSD will allow all authenticated users to login instead of denying access. (CVE-2018-16838)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL sssd packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
