descriptionThe Microsoft Office Products are missing security updates. They are, therefore, affected by multiple vulnerabilities: - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. (CVE-2019-0538, CVE-2019-0582) - A security feature bypass vulnerability exists when Microsoft Office does not validate URLs. An attacker could send a victim a specially crafted file, which could trick the victim into entering credentials. An attacker who successfully exploited this vulnerability could perform a phishing attack. (CVE-2019-0540) - An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of its memory. An attacker who exploited the vulnerability could use the information to compromise the user
