Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2008-0081)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when handling macros in Excel files. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
Note: this vulnerability was being actively exploited.
2) Memory corruption (CVE-ID: CVE-2008-0117)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when conditional formatting values handling in Excel files. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
3) Remote code execution (CVE-ID: CVE-2008-0116)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when loading application data into memory. A remote attacker can create a specially crafted Excel file with rich text values, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
4) Remote code execution (CVE-ID: CVE-2008-0115)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when handling Excel files. A remote attacker can create a specially crafted Excel file containing malformad formulas, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
5) Memory corruption (CVE-ID: CVE-2008-0114)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when handling data Style record in Excel files. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
6) Memory Corruption (CVE-ID: CVE-2008-0112)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when importing files into Excel. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
7) Memory corruption (CVE-ID: CVE-2008-0111)
The vulnerability alows a remote attacker to execute arbitrary code on the target system.The weakness exists due to a boundary error when processing data validation records in Excel files. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
