NVD Description

Note: Versions mentioned in the description apply only to the upstream qt package and not the qt package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
