CVE-2026-104065

Scribus before 1.6.7 and 1.7.x before 1.7.4 Heap Out-of-Bounds Write via Micrografx Draw Import

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an out-of-bounds write vulnerability in the importdrw Micrografx Draw plugin that uses an unvalidated y offset to select image scanlines. Attackers can craft a DRW file that, when imported by a user, writes decoded bitmap data outside the heap image buffer, causing crashes or code execution.

CVE-2026-104061

Scribus before 1.6.7 and 1.7.x before 1.7.4 Heap Out-of-Bounds Write via PSD Image Loader

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains a heap out-of-bounds write vulnerability in the scimgdataloader_psd loader that uses unchecked PSD file values as lookup array indexes. Attackers can convince users to place or import a crafted PSD file to corrupt heap memory, causing crashes and potentially code execution as the user.

CVE-2026-104064

Scribus before 1.6.7 and 1.7.x before 1.7.4 Heap Overflow via TIFF Tile Buffer Handling

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an integer overflow vulnerability in the scimgdataloader_tiff TIFF loader that allows attackers to trigger a heap overflow via crafted tile dimensions. Attackers can supply a tiled TIFF with large tile width, height and sample values for a user to import, corrupting heap memory to crash Scribus or execute code.

CVE-2026-104067

Scribus before 1.6.7 and 1.7.x before 1.7.4 Out-of-Bounds Memory Access via SVM Import Plugin

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an out-of-bounds memory access vulnerability in the importsvm plugin that fails to verify bitmap and transparency mask dimensions match. Attackers can supply a crafted SVM file with mismatched mask dimensions to trigger heap reads and writes, causing crashes or code execution as the user.

CVE-2026-104062

Scribus before 1.6.7 and 1.7.x before 1.7.4 Heap Buffer Overflow via PICT Pixmap Loader

Scribus before 1.6.7 and 1.7.x before 1.7.4 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.

CVE-2026-104063

Scribus before 1.6.7 and 1.7.x before 1.7.4 Out-of-Bounds Read via PICT Planar Image Data

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an out-of-bounds read vulnerability in the Mac PICT image loader and import plugin when decoding planar pixel data. Attackers can supply a crafted PICT file with manipulated dimensions that, when placed or imported, causes heap over-reads leading to crashes or heap memory disclosure.

CVE-2026-104066

Scribus before 1.6.7 and 1.7.x before 1.7.4 Heap Buffer Overflow via PICT 4-bit Pixel Unpacking

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains a heap buffer overflow vulnerability in the Mac PICT image loader and import plugin when unpacking 4-bit indexed pixel data. Attackers can supply a crafted PICT file with inconsistent width and row data that, when placed or imported, writes out of bounds, causing crashes or code execution.
