| win-ms08kb956416-update (45581) |  High Risk |
Description:
Microsoft Knowledge Base Article 956416 is not installed, which could allow a remote attacker to exploit the following vulnerabilities:
Microsoft Excel could allow a remote attacker to execute arbitrary code on the system, caused by improper validation of calendar object data in the VBA Performance Cache. By persuading a victim to open a specially-crafted Office Excel file, a remote attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system with the privileges of the victim.
Microsoft Excel is vulnerable to a stack-based buffer overflow, caused by improper processing of the Microsoft Excel spreadsheet BIFF file format. By persuading a victim to open a specially-crafted Office Excel file, a remote attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system with the privileges of the victim.
Microsoft Excel could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the REPT function. By persuading a victim to open a specially-crafted Office Excel file, a remote attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system with the privileges of the victim.
