Summary
ImageMagick has a Memory Leak in magick stream
Details

Summary

In ImageMagick's magick stream command, specifying multiple consecutive %d format specifiers in a filename template causes a memory leak.

Details

  • Vulnerability Type: Memory leak
  • Affected Version: ImageMagick 7.1.1-47 (as of commit 82572afc, June 2025)

Reproduction

Tested Environment

  • Operating System: Ubuntu 22.04 LTS
  • Architecture: x86_64
  • Compiler: gcc with AddressSanitizer (gcc version: 11.4.0)

Reproduction Steps

```bash

Clone source

git clone --depth 1 --branch 7.1.1-47 https://github.com/ImageMagick/ImageMagick.git ImageMagick-7.1.1 cd ImageMagick-7.1.1

Build with ASan

CFLAGS="-g -O0 -fsanitize=address -fno-omit-frame-pointer" CXXFLAGS="$CFLAGS" LDFLAGS="-fsanitize=address" ./configure --enable-maintainer-mode --enable-shared && make -j$(nproc) && make install

Trigger crash

./utilities/magick stream %d%d a a ```

Output

`` $ magick stream %d%d a a stream: no decode delegate for this image format' @ error/constitute.c/ReadImage/746. stream: missing an image filename `a' @ error/stream.c/StreamImageCommand/755.
