Description Michael Kaplan 2020-04-29 13:06:51 UTC

An exploitable out-of-bounds write vulnerability exists in the read_MSAT function of libxls 1.4. A specially crafted XLS file can cause a memory corruption resulting in remote code execution. An attacker can send malicious XLS file to trigger this vulnerability.
