Microsoft Office Works WPS Converter contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code. Updates are available.
Microsoft Office Works WPS Converter contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to improper validation of the .wps (Microsoft Works) file format by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to open a crafted .wps file with the affected software. If successful, the attacker could execute arbitrary code on the system with the privileges of the user.
Microsoft has confirmed this vulnerability in a security bulletin and has released updated software.
The following Microsoft products are vulnerable:
Microsoft Works 6-9 File Converter
Microsoft Office 2007 SP2
Microsoft Works 9.0
To exploit the vulnerability, the attacker may provide a file or a link to a malicious website and use misleading language or instructions to persuade the user to open the file or follow the provided link.
A successful exploit could allow the attacker to execute arbitrary code with the privileges of the targeted user.
Microsoft has corrected this vulnerability by deprecating the vulnerable Microsoft Works converter.
Microsoft has released a security bulletin at the following link: MS12-028
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system with the privileges of the user. If the user holds elevated privileges, the attacker could gain complete control over the system.
The vulnerability is due to improper validation of Microsoft Works .wps file format by the affected software.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to open a .wps file that contains crafted content with the affected software. When processed, the malicious content could cause a heap overflow memory corruption error. The attacker could take advantage of the memory corruption to execute arbitrary code on the system with the privileges of the user.
