Fight Against China's Web Filtering Software Grows
A U.S. company that says its code was copied by a Chinese Internet filtering program has ordered more PC makers not to distribute the Chinese software.
Chinese Internet users have also filled Twitter streams and online forums with opposition to Green Dam.
Programming errors that left Green Dam vulnerable to some attacks have been patched since the University of Michigan researchers revealed them last week, their updated report says.
But a properly designed IP (Internet Protocol) address could still take control of a user's computer through holes that remain in the patched program, the report says.
The researchers again advised uninstalling the program, calling it unlikely that all of its security problems could be fixed before the deadline for its distribution with PCs.
One patch also updated Green Dam's help file with a license statement for OpenCV, an open source computer vision package developed by Intel, the report said. Green Dam's image recognition tool for pornographic images draws on the package, according to the report.
Earlier versions appeared to violate OpenCV's license by leaving out its text, the report said.
A Chinese foreign ministry spokesman defended China's support for the program and declined to answer a question on its use of copied code at a press briefing Thursday.
"China has the responsibility and the obligation to protect its youth from violation by harmful online information," the spokesman said.
