CVE-2020-35492 – cairo: libreoffice slideshow aborts with stack smashing in cairo's composite_boxes
https://notcve.org/view.php?id=CVE-2020-35492
A flaw was found in cairo's image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo's image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo en el archivo image-compositor.c de cairo en todas las versiones anteriores a 1.17.4. Este fallo permite a un atacante que puede proporcionar un archivo de entrada diseñado al compositor de imágenes de cairo (por ejemplo, convenciendo a un usuario de abrir un archivo en una aplicación usando cairo, o si la aplicación usa cairo en una entrada que no es confiable) para causar un desbordamiento de búfer de la pila. -) ESCRITURA fuera de límites. • https://bugzilla.redhat.com/show_bug.cgi?id=1898396 https://security.gentoo.org/glsa/202305-21 https://access.redhat.com/security/cve/CVE-2020-35492 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
