char/tpm: zero buffer after copying to userspace
The fix for this issue has hit lucid, oneiric and precise via mainline
and stable. Following this email are three patches, one for hardy, one
for lucid/fsl-imx51, maverick and maverick/ti-omap4, and one for natty
and natty/ti-omap4. The hardy patch is a very minor backport, the other
two are simple cherry-picks only differing in context.
Proposing for hardy, lucid/fsl-imx51, maverick, maverick/ti-omap4, natty
I agree with Seth that this driver has some race problems. Also, I think
the patch for this CVE might be incomplete. I'll send the maintainer a
patch or two.
