Descriptions
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.
La clase QSharedMemory en Qt v5.0.0, v4.8.x anterior a v4.8.5, v4.7.x anterior a v4.7.6, y otras versiones incluida la v4.4.0 utiliza permisos débiles (escritura y lectura para todos los usuarios) para segmentos de memoria compartida, lo que permite a usuarios locales leer informacion sensible o modificar datos críticos del programa, como se demostró mediante la lectura de un pixmap enviado al servidor X.
Qt is a software toolkit that simplifies the task of writing and maintaining GUI applications for the X Window System. It was discovered that the QSharedMemory class implementation of the Qt toolkit created shared memory segments with insecure permissions. A local attacker could use this flaw to read or alter the contents of a particular shared memory segment, possibly leading to their ability to obtain sensitive information or influence the behavior of a process that is using the shared memory segment.
