Vulnerability Title

Scribus before 1.6.7 Heap Buffer Overflow via PICT Pixmap Loader

Source: CVE Program / CVE List V5

Vulnerability Description

Scribus before 1.6.7 contains a heap buffer overflow vulnerability in the PICT image loader and import plugin that allows attackers to corrupt heap memory by supplying an unchecked bytesPerLine value. Attackers can craft a PICT file whose bytesPerLine exceeds the QImage scanline size, so placing or importing it crashes Scribus and may execute code as the user.
