Descriptions

An issue was discovered in certain Apple products. iOS before 11.4 is affected. Safari before 11.1.1 is affected. iCloud before 7.5 on Windows is affected. iTunes before 12.7.5 on Windows is affected. tvOS before 11.4 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a crafted web site.

Se ha descubierto un problema en algunos productos Apple. Las versiones de iOS anteriores a la 11.4 se han visto afectadas. Se han visto afectadas las versiones de Safari anteriores a la 11.1.1, las versiones de iCloud anteriores a la 7.5 en Windows, las versiones de iTunes anteriores a la 12.7.5 en Windows y las versiones de tvOS anteriores a la 11.4. El problema afecta al componente "WebKit". Permite que los atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (desbordamiento de búfer o cierre inesperado de la aplicación) mediante un sitio web manipulado.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of SVG elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
