CVE-2024-24975
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUncontrolled Resource Consumption in Mattermost Mobile versions before 2.13.0 fails to limit the size of the code block that will be processed by the syntax highlighter, allowing an attacker to send a very large code block and crash the mobile app.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceUncontrolled resource consumption in Mattermost Mobile's syntax highlighter allows attackers to send oversized code blocks that crash the mobile app due to unbounded processing. The vulnerability stems from missing size limits on code blocks before they are passed to the syntax highlighter, causing memory exhaustion and app termination.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Mattermost Mobile app versionOpen the Mattermost Mobile app, navigate to Settings > About > Version, or check the app version in your device's app store or installed apps listAffected if The displayed version number is lower than 2.13.0 (for example, 2.12.0, 2.12.1, 2.12.2, etc.)
-
Verify if large code blocks can be receivedObserve if the app receives messages containing large code blocks (multi-line text enclosed in triple backticks) from other users or channelsAffected if Large code blocks are received and the app becomes unresponsive, crashes, or terminates unexpectedly after viewing them
You are affected if your Mattermost Mobile version is below 2.13.0 and you receive oversized code blocks in messages, which can cause the app to crash due to memory exhaustion.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.13.0
Upgrade Mattermost Mobile to version 2.13.0 or later, which implements proper size limits on code blocks processed by the syntax highlighter to prevent resource exhaustion.
2.13.0
- 1. Open the Mattermost Mobile app on your device
- 2. Navigate to the app settings or account settings
- 3. Check the current app version under 'About' or 'Version'
- 4. If the version is below 2.13.0, update the app through your device's app store (Apple App Store or Google Play Store)
- 5. Ensure the updated version is 2.13.0 or later
