Improper authentication in some Zoom clients before version 5.16.5 may allow an authenticated user to conduct a denial of service via network access.

Insufficient control flow management in some Zoom clients may allow an authenticated user to conduct an information disclosure via network access.

Improper authorization in some Zoom clients may allow an authorized user to conduct an escalation of privilege via network access.

Buffer overflow in some Zoom clients may allow an unauthenticated user to conduct a denial of service via network access.

Improper conditions check in Zoom Team Chat for Zoom clients may allow an authenticated user to conduct a denial of service via network access.

Buffer overflow in some Zoom clients may allow an unauthenticated user to conduct a denial of service via network access.

Cryptographic issues with In-Meeting Chat for some Zoom clients may allow a privileged user to conduct an information disclosure via network access.

Improper authentication in Zoom clients may allow an authenticated user to conduct a denial of service via network access.

Improper input validation in Zoom Desktop Client for Linux before version 5.15.10 may allow an unauthenticated user to conduct a denial of service via network access.

Exposure of sensitive information in Zoom Client SDK's before 5.15.5 may allow an authenticated user to enable a denial of service via network access.

Client-side enforcement of server-side security in Zoom clients before 5.14.10 may allow a privileged user to enable information disclosure via network access.

Client-side enforcement of server-side security in Zoom clients before 5.14.10 may allow an authenticated user to enable information disclosure via network access.

Buffer overflow in Zoom Clients before 5.14.5 may allow an unauthenticated user to enable a denial of service via network access.

Zoom clients prior to 5.13.10 contain an HTML injection vulnerability. A malicious user could inject HTML into their display name potentially leading a victim to a malicious website during meeting creation.

Zoom for Linux clients prior to 5.13.10 contain an HTML injection vulnerability. If a victim starts a chat with a malicious user it could result in a Zoom application crash.

The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.11.0 are susceptible to a URL parsing vulnerability. If a malicious Zoom meeting URL is opened, the malicious link may direct the user to connect to an arbitrary network address, leading to additional attacks including the potential for remote code execution through launching executables from arbitrary paths.

Zoom clients on Windows (before version 4.1.34814.1119), Mac OS (before version 4.1.34801.1116), and Linux (2.4.129780.0915 and below) are vulnerable to unauthorized message processing. A remote unauthenticated attacker can spoof UDP messages from a meeting attendee or Zoom server in order to invoke functionality in the target client. This allows the attacker to remove attendees from meetings, spoof messages from users, or hijack shared screens.

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.

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.
