CVE-2024-25385

What it actually does

Local denial of service via crash in flv_close at flv.c:375:21 when processing certain inputs.

Why it matters to the business

Disrupts local media file processing workflows that rely on this tool, causing operational interruptions with low urgency given age and lack of known exploitation.

How an attack unfolds

A local attacker supplies a crafted FLV file to the flvmeta binary; processing triggers the flaw in flv_close resulting in application crash and denial of service. No named threat actors or ransomware usage reported.

How to fix it

Upgrade flvmeta to a version beyond 1.2.2 if a fix is released; otherwise replace the tool with a maintained alternative and remove the vulnerable binary from use.

How to confirm the fix worked

Run flvmeta version check and test against known crashing FLV samples in a lab environment to confirm resolution or continued exposure.

Typical attack path

1. Locate flvmeta binary on accessible system
2. Prepare malicious FLV input file targeting the flv_close path
3. Invoke flvmeta against the crafted file to induce crash

How to detect it

Review system and application logs for unexpected flvmeta process terminations or segmentation faults during FLV processing; no widespread exploitation indicators available.

What your security team should do

• Inventory all systems using flvmeta and remove or isolate the binary
• Monitor for any new fixed releases and apply promptly
• Substitute with actively maintained FLV tooling
