https://notcve.org/view.php?id=CVE-2020-25690
An out-of-bounds write flaw was found in FontForge in versions before 20200314 while parsing SFD files containing certain LayerCount tokens. This flaw allows an attacker to manipulate the memory allocated on the heap, causing the application to crash or execute arbitrary code. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo de escritura fuera de límites en FontForge en versiones anteriores a 20200314 mientras se analizan archivos SFD que contienen determinados tokens LayerCount. Este fallo permite a un atacante manipular la memoria asignada en la pila, causando a la aplicación bloquearse o ejecutar código arbitrario. • https://bugzilla.redhat.com/show_bug.cgi?id=1893188 https://access.redhat.com/security/cve/CVE-2020-25690 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
