-Subject: [PATCH] ARM: Don't extend bit LG_VADDR to compute high address bits.
-
-In userspace ARM on Linux, zero-ing the high bits is the correct way to do this.
-This doesn't fix the fact that we currently set LG_VADDR to 48 on ARM, when in
-fact larger virtual address sizes are coming soon.  We'll cross that bridge when
-we come to it.

-Subject: [PATCH] Add blinding to an ECDSA signature
-
-Keegan Ryan (NCC Group) has demonstrated a side channel attack on an
-ECDSA signature operation. During signing the signer calculates:
-
-s:= k^-1 * (m + r * priv_key) mod order
-
-The addition operation above provides a sufficient signal for a
-flush+reload attack to derive the private key given sufficient signature
-operations.
-
-As a mitigation (based on a suggestion from Keegan) we add blinding to
-the operation so that:
-
-s := k^-1 * blind^-1 (blind * m + blind * r * priv_key) mod order
-
-Since this attack is a localhost side channel only no CVE is assigned.
-

-Subject: Prevent directory chmod race attack.
-
-CVE-2017-6512 is a race condition attack where the chmod() of directories
-that cannot be entered is misused to change the permissions on other
-files or directories on the system. This has been corrected by limiting
-the directory-permission loosening logic to systems where fchmod() is
-supported.
-
-[Backported (whitespace adjustments) to File-Path 2.12 / perl 5.24 by
-Dominic Hargreaves for Debian.]
