SPI: SCK input too sensitive?

I'm using the SPI (slave mode) of an S12XA256 to sample serial data from another device (clock frequency is ~500kHz). At roughly 1..2-hourly intervals there seems to be a glitch on SCK that disturbs SPI and shifts in an additional bit. How can I get rid of that? I fiddled around with low-pass filters but it doesn't work until now...

Anyone can help?
Thanks in advance,
