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,

Patch to g15daemon-1.9.5.3-r3.ebuild to resolve reported overflow

Upstream uses a hardcoded size of 10 for recv, but passes a buffer that is only int[2], which is too small.  It happens to work for the intended use since they really only expect to receive 1 byte, but this patch fixes it so that the argument to recv specifies the proper length.

Fixed in r4 (used the patch from the other bug).
