CVE-2011-1758 high priority: Ubuntu including 1 source packages (sssd), 7 status rows across 7 suites (dapper, hardy, lucid, maverick, natty, oneiric, upstream): not-affected 4, DNE 2, released 1.
The krb5_save_ccname_done function in providers/krb5/krb5_auth.c in System Security Services Daemon (SSSD) 1.5.x before 1.5.7, when automatic ticket renewal and offline authentication are configured, uses a pathname string as a password, which allows local users to bypass Kerberos authentication by listing the /tmp directory to obtain the pathname.
