Low risk6th percentile - higher than 6% of all known CVEs
Summary
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. An attacker can supply a crafted PICT file with manipulated dimensions, causing heap over-reads leading to crashes or heap memory disclosure.
Risk Assessment
Opening or importing a malicious PICT file can crash the application or leak heap memory contents. This may lead to disclosure of sensitive information or destabilization of the user environment.
Recommendation
Upgrade Scribus to version 1.6.7 or 1.7.4 (or later). Avoid opening PICT files from untrusted sources until patched.
Other vulnerabilities in Scribus
See all- CVE-2026-104067High
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-2026-104066High
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.
- CVE-2026-104065High
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-2026-104064High
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-2026-104062High
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-2026-104061High
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.
