DLA-1635-1 sssd -- LTS security update

Date Reported:

17 Jan 2019

Affected Packages:

sssd

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 919051.
In Mitre's CVE dictionary: CVE-2019-3811.

More information:

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.

For Debian 8 Jessie, this problem has been fixed in version 1.11.7-3+deb8u2.

We recommend that you upgrade your sssd packages.
