CVE-2026-4756 — AI Deep Analysis Summary

🚨 **Out-of-Bounds Write Vulnerability** • Nature: Memory out-of-bounds write in Android-ImageMagick7 image processing library • Impact: 💥 Local code execution, privilege escalation, complete device compromise

🔍 **CWE-787: Out-of-bounds Write** • Flaw: Buffer boundary validation failure during image parsing • Trigger: Writing to illegal memory addresses when processing maliciously crafted image files

📱 **MolotovCherry/Android-ImageMagick7** • Affected: ImageMagick7 port for Android platform • Specific versions: Not specified, check versions prior to 2026-03-24

👿 **Attacker Capabilities:** • 🎯 **Local Code Execution** (C:H / I:H / A:H) • 🔓 High-privilege operations (sandbox bypass, sensitive data theft) • 📸 Camera/gallery permission abuse (image processing scenarios)

⚠️ **Barrier: Medium-Low** • AV:L → Requires **local access** (not remote) • AC:L → Simple exploitation conditions • PR:N → **No authentication required** • UI:R → Requires user interaction (opening malicious image)

❌ **No Public PoC Available** • Official repository: 0 public exploits • 🔔 Risk: Patch released, rapid development possible after reverse engineering

🔎 **Self-Check Methods:** • Check if app depends on `Android-ImageMagick7` • Review library version in `build.gradle` • Monitor abnormal crash logs (SIGSEGV/SIGABRT)

✅ **Fixed!** • 📌 Patch: GitHub PR #194 • 🔗 https://github.com/MolotovCherry/Android-ImageMagick7/pull/194 • Date: Coordinated disclosure on 2026-03-24

🛡️ **Temporary Mitigations:** • Disable external image processing features • Sandbox isolation of ImageMagick processes • Input validation: limit image size/format • Monitor abnormal memory access behavior

🔥 **Priority: HIGH** | Factor | Assessment | |--------|------------| | CVSS 3.1 | **7.8** (High) | | Attack Vector | Local + user interaction, but no authentication required | | Patch Status | ✅ Available, immediate upg…
