Integer overflow due to missing input sanitation in rdpegfx channel. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a memcpy) (CVE-2020-15103).

Open-iSCSI rtslib-fb through 2.1.72 has weak permissions for /etc/target/saveconfig.json because shutil.copyfile (instead of shutil.copy) is used and thus permissions are not preserved upon editing. An adversary with prior access to /etc/target/saveconfig.json could access a later version, resulting in a loss of integrity depending on their permission settings
