Name of the Vulnerable Software and Affected Versions libxls version 1.4

Description An integer overflow issue exists in the xls preparseWorkSheet function when handling a MULRK record, allowing a specially crafted XLS file to cause memory corruption and potentially result in remote code execution. An attacker can exploit this by sending a malicious XLS file.

Recommendations For libxls version 1.4, consider avoiding the use of the xls preparseWorkSheet function until a patch is available, or refrain from handling untrusted XLS files to minimize the risk of exploitation.
