CVE-2022-22629

Se abordó un problema de desbordamiento de búfer con un manejo de memoria mejorado. Este problema ha sido corregido en macOS Monterey versión 12.3, Safari versión 15.4, watchOS versión 8.5, iTunes versión 12.12.3 para Windows, iOS versión 15.4 y iPadOS versión 15.4, tvOS versión 15.4. El procesamiento de contenido web diseñado de forma maliciosa puede conllevar a una ejecución de código arbitrario.

A buffer overflow vulnerability was found in WebKitGTK and WPE WebKit. This flaw allows a remote attacker to process maliciously crafted web content, leading to arbitrary code execution.

This vulnerability allows remote attackers to execute arbitrary code on affected 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 WebGLMultiDraw component. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user.

Juraj Somorovsky, Marcel Maehren, Nurullah Erinola, and Robert Merget discovered that the DTLS implementation in the JSSE subsystem of OpenJDK did not properly restrict handshake initiation requests from clients. A remote attacker could possibly use this to cause a denial of service. Markus Loewe discovered that the Java Sound subsystem in OpenJDK did not properly validate the origin of a Soundbank. An attacker could use this to specially craft an untrusted Java application or applet that could load a Soundbank from an attacker controlled remote URL.
