Description Diego Elio Pettenò (RETIRED) gentoo-dev

You're receiving this bug because the package in Summary has produced _FORTIFY_SOURCE related warnings indicating the presence of a sure overflow in a static buffer.

Even though this is not always an indication of a security problem it might even be. So please check this out ASAP.

By the way, _FORTIFY_SOURCE is disabled when you disable optimisation, so don't try finding out the cause using -O0.

Thanks,
Your friendly neighborhood tinderboxer

There isn't any QA warning, or "will always overflow destination buffer" warning during compile.

I use

CFLAGS="-march=athlon64 -O2 -pipe -msse3"

So I think this potential security problem is fixed by upstream.
