SB2009111001 - Multiple vulnerabilities in Microsoft Office

Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) Memory corruption (CVE-ID: CVE-2009-3127)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when parsing of the Excel spreadsheet file format. A remote attacker can create a specially crafted .xls file, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

2) Memory corruption (CVE-ID: CVE-2009-3128)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when parsing of the Excel spreadsheet file format. A remote attacker can create a specially crafted .xls file containing a malformed record object, trick the victim into opening it, trigger SxView memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

3) Memory corruption (CVE-ID: CVE-2009-3129)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when parsing of the Excel spreadsheet file format. A remote attacker can create a specially crafted .xls file containing a malformed record object, trick the victim into opening it, trigger Featheader record memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

4) Heap-based buffer overflow (CVE-ID: CVE-2009-3130)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to heap-based buffer overflow when parsing of the Excel spreadsheet file format. A remote attacker can create a specially crafted .xls file containing malformed Binary File Format (BIFF) records, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

5) Memory corruption (CVE-ID: CVE-2009-3131)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when parsing of the Excel spreadsheet file format. A remote attacker can create a specially crafted .xls file containing a malformed formula embedded inside a cell, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

6) Memory corruption (CVE-ID: CVE-2009-3132)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to pointer corruption error when loading Excel formulas. A remote attacker can create a specially crafted .xls file containing a malformed formula, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

7) Memory corruption (CVE-ID: CVE-2009-3133)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to heap-based buffer overflow when loading Excel records. A remote attacker can create a specially crafted .xls file containing a malformed object, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.

8) Memory corruption (CVE-ID: CVE-2009-3134)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when parsing of the Excel spreadsheet file format. A remote attacker can create a specially crafted .xls file containing a malformed record object, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.
