Amazon Linux 2 Security Advisory: ALAS-2019-1343
Advisory Release Date: 2019-10-28 17:45 Pacific
Advisory Updated Date: 2019-10-30 21:09 Pacific
Severity:
Medium
Issue Overview:
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)
A vulnerability was found in sssd where, 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().(CVE-2019-3811)
Affected Packages:
