El procesamiento de contenido web creado con fines malintencionados puede provocar la divulgación de la memoria del proceso.
A flaw was found in webkitgtk. Improper input validation leads to a memory corruption vulnerability. This flaw allows an attacker with network access to pass specially crafted web content files, causing an application to halt, crash, or perform arbitrary code execution.
This vulnerability allows remote attackers to disclose sensitive information 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 DFG JIT. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
