CVE-2023-32029 [HIGH] Two remote code execution vulnerabilities disclosed in Microsoft Excel
Cisco Talos recently discovered two vulnerabilities in the Microsoft Excel spreadsheet management software that could allow a malicious actor to execute arbitrary code on the targeted machine.
Microsoft disclosed these issues and patched them as part of June’s monthly security release for the company.
One of the vulnerabilities, TALOS-2023-1730 (CVE-2023-32029), exists in the FreePhisxdb function of Excel. An attacker could exploit this vulnerability by tricking the targeted user into opening a specially crafted file. Then, they can manipulate the heap to gain the ability to execute arbitrary code.
TALOS-2023-1734 (CVE-2023-33133) works similarly, but in this case, causes an out-of-bounds read that turns into an out-of-bounds write, which in turn, could lead to memory corruption and, fi
