Description

The QSharedMemory class in Qt 5.0.0 4.8.x before 4.8.5 4.7.x before 4.7.6 and other versions including 4.4.0 uses weak permissions (world-readable and world-writable) for shared memory segments which allows local users to read sensitive information or modify critical program data as demonstrated by reading a pixmap being sent to an X server.
