The fix is in

 E-Mail The need to patch a problem in a program that is embedded in an existing system, perhaps to introduce or enhance security, is a common one, according to UC Santa Barbara computer science professor Giovanni Vigna. But, why would you do that? he asks rhetorically. Why not just write a different program? Because sometimes it s not possible, or it would require a very substantial effort, he answers. Sometimes, you re given a program to patch, and you don t have the source code to modify it at that level and recompile it. Many embedded computer systems, such as those in trucks, airplanes and medical devices, run on software for which the source code and the original compilation toolchain are unavailable, said Antonio Bianchi, an assistant professor at Purdue University who studied in Vigna s lab while pursuing his doctorate at UCSB. Many old software components running in these systems are known to contain vulnerabilities, but patching them is not always easy or eve

Patching Still Poses Problems for Industrial ...

Patching Still Poses Problems for Industrial Controllers, Networking Devices More than 90% of devices that run popular embedded operating systems remain vulnerable to critical flaws disclosed more than a year ago. Two families of critical vulnerabilities that impact operational technology (OT), embedded devices, and network hardware continue to undermine the security of the vast majority of originally affected devices because patching the issues has been glacially slow, according to a new research report by device-security firm Armis.    Using random sampling, the company checked the patch status of devices vulnerable to flaws affecting seven vulnerable embedded operating systems, including the widespread VxWorks, which it had disclosed in July and October 2019, finding that 97% of devices have not been updated to a patched version of the software. The company also scanned a subset of Cisco network, IP phone, and camera devices for a set of five vulnerabilities disclosed in Febr
