Zoom security teams announced the release of patches for two vulnerabilities that could affect Windows, iOS, macOS, Android and Linux users. Reported by Google Project Zero, the flaws reside in the Zoom client for major platforms and their exploitation would allow the deployment of code execution attacks.

Tracked as CVE-2021-34423, the first of the flaws is considered to be of high severity and could also affect other components and software development kits (SDK). According to Zoom, this would allow threat actors blocking the affected services or applications, in addition to forcing arbitrary code execution.

The second vulnerability, tracked as CVE-2021-34424, was described as a memory corruption error that would allow the state of the process memory to be exposed in various processes in multiple products and components: “The flaw could be exploited to obtain information about arbitrary areas in the memory of the affected product,” the report states.

Among the affected products are:

  • Zoom Client for Meetings for Android, iOS, Linux, macOS and Windows, versions earlier than 5.8.4
  • Zoom Client for Meetings for Blackberry (iOS and Android) versions earlier than 5.8.1
