Description Martin Prpič 2015-03-09 09:50:03 UTC
An uninitialized data structure flaw was found in lasso, a library that implements SSO standards. A remote attacker could potentially use this flaw to crash an application using the lasso library.

The lasso library is used by ipsilon and mod_auth_mellon.
