40+ CVE-2019-7309
41+ * NEWS: Updated for CVE-2019-7309.
42+ * sysdeps/x86_64/memcmp.S: Use RDX_LP for size. Clear the
43+ upper 32 bits of RDX register for x32. Use unsigned Jcc
44+ instructions, instead of signed.
45+ * sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memcmp-2.
46+ * sysdeps/x86_64/x32/tst-size_t-memcmp-2.c: New test.
