-Subject: extensionSystem: handle reloading broken extensions

-we need to catch any exceptions so that we don't leave things in
-a broken state that could lead to leaving extensions enabled in
-the screen shield.

+Fix "Hostname" parsing in OpenSSH config files, as reported
+at <https://red.libssh.org/issues/260>.
+
+From: Niels Ole Salscheider <niels_ole@salscheider-online.de>
+Date: Mon, 8 May 2017 17:36:13 +0200
+Subject: [PATCH] Fix reading of the first parameter
+
+This is a fixup for 7b8b5eb4eac314a3a29be812bef0264c6611f6e7.
+Previously, it would return as long as the parameter was _not_ seen
+before. It also did not handle the case for the unsupported opcode (-1)
+which would cause a segfault when accessing the "seen" array.

+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.]
