**Name of the Vulnerable Software and Affected Versions** Mattermost Mobile Apps versions <=2.25.0 **Description** The issue is related to the improper validation of GIF images prior to rendering, which allows a malicious user to cause the Android application to crash via a message containing a maliciously crafted GIF. **Recommendations** For Mattermost Mobile Apps versions <=2.25.0, update to a version greater than 2.25.0 to resolve the issue. As a temporary workaround, consider avoiding the use of GIF images in messages until a patch is available. Restrict access to untrusted messages to minimize the risk of exploitation.
