QT TIFF Processing Out-Of-Bounds Read
Posted by deepcore on May 25, 2021 – 10:07 pm
The QImageReader class can read out-of-bounds when converting a specially-crafted TIFF file into a QImage, where the TIFF tile length is inconsistent with the tile size. This could potentially allow an attacker to determine values in memory based of the QImage pixels, if QT is used to process untrusted images.
