Technical details
A stack overflow vulnerability exists in the Qt SVG module's handling of SVG files. The issue occurs when the renderer encounters a <pattern> element that references itself or creates a circular dependency, leading to infinite recursion during the rendering process. An attacker can exploit this by providing a malformed SVG file to any application using the affected Qt library. This results in a crash (Denial of Service) due to stack exhaustion. A patch has been developed for the qtsvg component to detect and prevent these recursive loops.
