Description

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

# 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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Magick.NET-Q16-AnyCPU, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update Magick.NET-Q16-AnyCPU to 14.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53019 is resolved across your whole dependency graph.

  3. Workarounds

    Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
