Known Zoom Vulnerabilities

Earlier this week, two vulnerabilities in the Zoom application for Mac devices were disclosed by a security researcher. These vulnerabilities include the use of a local host web server on Mac devices to operate Zoom, and the way in which video is enabled for Zoom meetings.

On 9 July, Zoom released an initial patch that allows Mac devices to operate Zoom without the use of a local host web server. The second patch, regarding potential misconfiguration of video settings, will be released over the weekend (13-14 July). 

We recommend reading the blog Zoom issued addressing these vulnerabilities, what steps they are taking, and what you may need to do.

From a data security perspective, Engineering & IT views these vulnerabilities as moderate rather than extreme. Despite the relatively low risk, Zoom took swift action to address these concerns and has been in contact with us throughout the process. We will remain in close contact with Zoom to ensure safe and secure service continues. I remain confident that Zoom is the right provider for our web conferencing needs. 

If you have any questions or concerns related to Zoom, please let us know.

    Thank you very much for the article and information.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
