|
|
|
|
|
<p>A Denial of Service flaw was found in the way Xlockmore performed
|
|
|
|
|
|
the passing of arguments to the underlying localtime() call, when the
|
|
|
|
|
|
‘dlock’ mode was used.

<impact type="normal">
|

|
|
|
|
<p>A local attacker could possibly cause a Denial of Service condition and

|
potentially obtain unauthorized access to the graphical session,
|
|
|
|
|
|
previously locked by another user.
