CVE-2024-48854
📋 TL;DR
An off-by-one error in the TIFF image codec in QNX SDP versions 8.0, 7.1, and 7.0 could allow an unauthenticated attacker to cause information disclosure in the context of the process using the image codec. This affects systems running vulnerable QNX SDP versions that process TIFF images.
💻 Affected Systems
- QNX Software Development Platform (SDP)
📦 What is this software?
Qnx Software Development Platform by Blackberry

⚠️ Risk & Real-World Impact
Worst Case
Sensitive memory contents from the process handling the TIFF image could be disclosed, potentially revealing credentials, keys, or other confidential data.
Likely Case
Limited information disclosure from the process memory space, potentially exposing non-critical data or causing application instability.
If Mitigated
No impact if TIFF image processing is disabled or systems are patched.
🎯 Exploit Status
Requires crafting a malicious TIFF image to trigger the off-by-one error. No public exploit code is known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://support.blackberry.com/pkb/s/article/140334
Restart Required: Yes
Instructions:
1. Review the BlackBerry advisory. 2. Apply the recommended patches from QNX. 3. Restart affected systems. 4. Verify the patch is applied correctly.
🔧 Temporary Workarounds
Disable TIFF image processing
allPrevent TIFF images from being processed by the vulnerable codec
Configuration depends on specific application usage - consult QNX documentation
Input validation for TIFF images
allImplement strict validation of TIFF images before processing
Implement file validation in applications using TIFF processing
🧯 If You Can't Patch
- Isolate systems from untrusted TIFF image sources
- Implement network segmentation to limit exposure
🔍 How to Verify
Check if Vulnerable:
Check QNX SDP version using 'uname -a' or system documentation. Versions 8.0, 7.1, or 7.0 are vulnerable.Check Version:
uname -aVerify Fix Applied:
Verify patch installation through QNX package management and confirm version is no longer vulnerable.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing TIFF images
- Memory access violations in TIFF processing
Network Indicators:
