Description Michael Kaplan 2020-04-29 12:59:17 UTC

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