+Subject: [PATCH] CVE-2017-1000366: Ignore LD_LIBRARY_PATH for AT_SECURE=1
+ programs [BZ #21624]
+
+LD_LIBRARY_PATH can only be used to reorder system search paths, which
+is not useful functionality.
+
+This makes an exploitable unbounded alloca in _dl_init_paths unreachable
+for AT_SECURE=1 programs.

+Subject: [PATCH] i686: Add missing IS_IN (libc) guards to vectorized strcspn
+
+Since commit d957c4d3fa48d685ff2726c605c988127ef99395 (i386: Compile
+rtld-*.os with -mno-sse -mno-mmx -mfpmath=387), vector intrinsics can
+no longer be used in ld.so, even if the compiled code never makes it
+into the final ld.so link.  This commit adds the missing IS_IN (libc)
+guard to the SSE 4.2 strcspn implementation, so that it can be used from
+ld.so in the future.
