CVE-2011-1758
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.
