Vulnerability from variot
An out-of-bounds read was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave. Processing a maliciously crafted font may lead to arbitrary code execution. Apple macOS is a set of dedicated operating systems developed by Apple Corporation for Mac computers. There is a security vulnerability in Apple macOS. The vulnerability originates from the boundary condition when handling font files in the FontParser component in macOS. A remote attacker could create a specially crafted file or web page that tricks a victim into opening the file, triggering an out-of-bounds read error and reading the contents of memory on the system. Vulnerabilities exist in the following products or versions: macOS 10.15, macOS 10.15 SU1, macOS 10.15.1, macOS 10.15.2, macOS 10.15.3, macOS 10.15.4, macOS 10.15.4 SU1, macOS 10.15.5, macOS 11.55.5 SU1 , macOS 15.65.6, macOS 10.15.6 SU1, macOS 10.15.7, 10.15.7 SU1, macOS 11.0, macOS 11.0.1, macOS 11.1
