Original NVD Description

The read_MSAT_body function in ole.c in libxls 1.4.0 has an invalid free that allows attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file, because of inconsistent memory management (new versus free) in ole2_read_header in ole.c.
