CVE-2024-44083
📋 TL;DR
IDA Pro versions through 8.4 contain a denial-of-service vulnerability in the ida64.dll component. When analyzing binaries with sections containing many jumps where the final jump corresponds to the payload entry point, the application crashes. This primarily affects reverse engineers and security analysts using IDA Pro for binary analysis.

⚠️ Risk & Real-World Impact
Worst Case
Complete denial-of-service causing IDA Pro to crash during analysis, potentially corrupting analysis databases and disrupting reverse engineering workflows.
Likely Case
Application crash when analyzing specially crafted binaries, requiring restart and potential loss of unsaved work.
If Mitigated
Minor inconvenience with occasional crashes during analysis of specific binary types.
🎯 Exploit Status
Proof-of-concept code is publicly available on GitHub. Exploitation requires the victim to analyze a specially crafted binary file.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: IDA Pro 8.5 or later
Vendor Advisory: https://hex-rays.com/
Restart Required: Yes
Instructions:
1. Download IDA Pro 8.5 or later from Hex-Rays website
2. Install the update following vendor instructions
3. Restart IDA Pro to apply the fix
🔧 Temporary Workarounds
Avoid suspicious binaries
allDo not analyze untrusted or suspicious binary files with vulnerable IDA Pro versions
Use alternative analysis tools
allUse Ghidra, Binary Ninja, or other reverse engineering tools for suspicious files
🧯 If You Can't Patch
- Restrict IDA Pro usage to trusted binaries only
- Implement regular save points during analysis to minimize data loss from crashes
