The read_MSAT function in ole.c in libxls 1.4.0 has a double free that allows attackers to cause a denial of service (application crash) via a crafted file, a different vulnerability than CVE-2017-2897.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
