nokia calendar memory errors

I have sent this to the security mail of nokia without success and to the
normal support contact with no response.

So I forward this I think could be interesting. I just see other strange
memory behaviour like the one described : a
calendar entry having the ending characters of another entry. And when I
change one entry this seems to change and
corrupting the other and vice versa.

I don't tested these problems on other nokia models.

A found something strange on my nokia 5210 and ask myself if it isn't a
bug
in the software.

I add a new entry on my calendar. But the last characters of my new entry
are changed with the square "" char. If I add a new entry with fewer
characters the entry is ok. Than I add another
entry
on a different date. My new entry isn't
correct and show only 3 squares "". Than I look in my previews entry
and
the last characters that was correct are now
not correct and show squares "". I think I have used my full memory for
calendar entry and it seems to act like a
"bufferoverflow" ?

I ask myself if security problems can rise if somebody send a new
calendar
entry via sms to somebody else this will
"delete" some characters of other entries in the phone ?...
So we can send a lot of new calendar entries to somebody
to "bufferoverflow"
is memory or delete personal informations ???

Could you give me feedback about this ?

Thank you.
