Stack-based buffer overflow in the ZoomLauncher binary in the Zoom client for Linux before 2.0.115900.1201 allows remote attackers to execute arbitrary code by leveraging the zoommtg:// scheme handler.

The ZoomLauncher binary in the Zoom client for Linux before 2.0.115900.1201 does not properly sanitize user input when constructing a shell command, which allows remote attackers to execute arbitrary code by leveraging the zoommtg:// scheme handler.

The ZOOM Cloud Meetings (aka us.zoom.videomeetings) application @7F060008 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Path Traversal in Zoom for Android Clients

Zoom for Android clients before version 5.13.0 contain a path traversal vulnerability. A third party app could exploit this vulnerability to read and write to the Zoom application data directory.

Zoom Clients - Business Logic Error

Business logic error in some Zoom clients may allow an authenticated user to conduct information disclosure via network access.

Information Disclosure in Zoom for Windows Clients

Zoom for Windows clients before version 5.13.3, Zoom Rooms for Windows clients before version 5.13.5 and Zoom VDI for Windows clients before 5.13.1 contain an information disclosure vulnerability. A recent update to the Microsoft Edge WebView2 runtime used by the affected Zoom clients, transmitted text to Microsoft’s online Spellcheck service instead of the local Windows Spellcheck. Updating Zoom remediates this vulnerability by disabling the feature. Updating Microsoft Edge WebView2 Runtime to at least version 109.0.1481.0 and restarting Zoom remediates this vulnerability by updating Microsoft’s telemetry behavior.

Zoom clients before version 5.13.5 contain a STUN parsing vulnerability. A malicious actor could send specially crafted UDP traffic to a victim Zoom client to remotely cause the client to crash, causing a denial of service.

Denial of Service in Zoom Clients

Zoom clients before version 5.13.5 contain a STUN parsing vulnerability. A malicious actor could send specially crafted UDP traffic to a victim Zoom client to remotely cause the client to crash, causing a denial of service.

Improper trust boundary implementation for SMB in Zoom Clients

Zoom clients prior to 5.13.5 contain an improper trust boundary implementation vulnerability. If a victim saves a local recording to an SMB location and later opens it using a link from Zoom’s web portal, an attacker positioned on an adjacent network to the victim client could set up a malicious SMB server to respond to client requests, causing the client to execute attacker controlled executables. This could result in an attacker gaining access to a user's device and data, and remote code execution.

Zoom for Windows clients prior to 5.13.5 contain an improper verification of cryptographic signature vulnerability. A malicious user may potentially downgrade Zoom Client components to previous versions.
