Bug#865549: linux-image-3.16.0-4-powerpc64le: stackguard fix incorrect; probably causes cargo to segfault on ppc64el
Package: linux-image-3.16.0-4-powerpc64le
Version: 3.16.43-2+deb8u1
Severity: critical
Justification: breaks unrelated software
Dear Maintainer,
I have been getting segfaults trying to build cargo on ppc64el
https://github.com/rust-lang/cargo/issues/4197
The signs point to the recent stack guard fix as being the culprit, I can
confirm that the test program given here:
http://www.openwall.com/lists/oss-security/2017/06/22/6
indicates the presence of the bug on plummer.debian.org. I'm not very familiar
with kernel development so I don't know where the proper fix is, but subsequent
discussion on that thread suggests that mainline has the "correct fix" whereas
some distros applied an incorrect one.
Thanks,
Ximin
