The zero-day is described as a memory corruption bug in the FreeType font rendering library and is tracked as CVE-2020-15999 that’s included with standard Chrome distributions.

One of Google’s internal security teams found this FreeType bug in-the-wild attacks discovered by security researchers from Project Zero.

Project Zero team lead Ben Hawkes says it is a threat actor was spotted abusing this FreeType bug which led to an attack against Chrome users.

Now, Hawkes has also urged other app vendors who are using the same FreeType library to update their software. This is because if the threat actor decides to shift attacks against other apps, they will deal with same consequences.

In the past twelve months, CVE-2020-15999 is the third zero-day exploited.
