REDHAT-BUG-700867
First published: Fri Apr 29 2011(Updated: )
A flaw was introduced in SSSD 1.5.0 that, under certain conditions, would have sssd overwrite a cached password with the filename of the kerberos credential store (defined by krb5_ccache_template in sssd.conf). This could allow an attacker to gain access to an account without knowing the password if they knew the cached-credential string. This flaw does not affect earlier versions of SSSD that did not have support for automatic ticket renewal services.
| Affected Software | Affected Version | How to fix |
|---|---|---|
| SUSE SSSD (System Security Services Daemon) with Kerberos 5 support | >1.5.0 |
