Additional information

In an attack scenario, threat actors would need to convince a victim to interact with a specially crafted font file. Reports of threat actors exploiting CVE-2020-1599 against vulnerable versions of Chrome have been identified. It is not clear if other vulnerable applications have been targeted at this time. Confirmed vulnerable web-browsers should be prioritized for patching as they have a higher likelihood of being exposed to untrusted code.

CVE-2020-15999 is classified as a Heap-based Buffer Overflow vulnerability in the open-source FreeType library. The FreeType library is incorporated into a wide variety of software, meaning multiple programs and operating systems other than Chrome are likely affected. Additional vendor updates are expected in the near future.
