VAR-201706-0390
Vulnerability from variot - Updated: 2023-12-26 22:22Use after free vulnerability in the String.replace method JavaScriptCore in Apple Safari in iOS before 10.3 allows remote attackers to execute arbitrary code via a crafted web page, or a crafted file. 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 the String.replace method. 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 vulnerability to execute code under the context of the current process. Failed exploit attempts will likely cause a denial-of-service condition. Both Apple Safari and iOS are products of the American company Apple (Apple). Apple Safari is a web browser that is the default browser included with the Mac OS X and iOS operating systems; iOS is an operating system developed for mobile devices. JavaScriptCore is one of those frameworks

"data": "Use after free vulnerability in the String.replace method JavaScriptCore in Apple Safari in iOS before 10.3 allows remote attackers to execute arbitrary code via a crafted web page, or a crafted file. 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 the String.replace method. 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 vulnerability to execute code under the context of the current process. Failed exploit attempts will likely cause a denial-of-service condition. Both Apple Safari and iOS are products of the American company Apple (Apple). Apple Safari is a web browser that is the default browser included with the Mac OS X and iOS operating systems; iOS is an operating system developed for mobile devices. JavaScriptCore is one of those frameworks",
