CVE-2017-17784

What it actually does

Heap-based buffer over-read in the GBR file import parser due to mishandling of UTF-8 data, enabling memory corruption that can lead to information disclosure or application crash.

Why it matters to the business

Potential exposure of sensitive memory contents or service disruption when processing untrusted image files; outdated packages increase risk of successful attacks in environments relying on these components.

How an attack unfolds

An attacker creates a specially crafted GBR file containing malformed UTF-8 sequences, then convinces a user to open it with the vulnerable software, triggering the over-read during parsing.

How to fix it

Upgrade grafana-fips-10.4 and grafana-fips-10.4-oci-compat to version 10.4.3-r1 or later; remove or isolate older package versions from build and runtime environments.

How to confirm the fix worked

Verify installed package versions match or exceed the fixed releases; test GBR import functionality with known-good and edge-case files to confirm stability.

Typical attack path

1. Craft malicious GBR file exploiting UTF-8 mishandling
2. Deliver file via email, download, or shared storage
3. Victim opens file using affected import functionality
4. Parser performs buffer over-read leading to memory access violation

How to detect it

Review application logs and crash reports for buffer over-read errors or segmentation faults during GBR file processing; examine file import activity for unexpected memory-related exceptions.

What your security team should do

• Prioritize upgrade to 10.4.3-r1 across all deployments within 30 days
• Scan container images and package repositories for affected versions
• Restrict opening of untrusted GBR files until patches are applied
• Monitor for new EPSS increases or exploit publications
