| Vetor | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
iOS versions prior to 10.3
Safari versions prior to 10.1
iCloud versions prior to 6.2 on Windows
iTunes versions prior to 12.6 on Windows
tvOS versions prior to 10.2
Description
The issue involves the WebKit component and allows remote attackers to execute arbitrary code or cause a denial of service, resulting in memory corruption and application crash, via a crafted web site. This is due to a use-after-free vulnerability, which occurs when memory is accessed after it has been freed. The exploitation of this vulnerability can lead to remote code execution or a denial of service.
Recommendations
For iOS versions prior to 10.3, update to version 10.3 or later.
For Safari versions prior to 10.1, update to version 10.1 or later.
For iCloud versions prior to 6.2 on Windows, update to version 6.2 or later.
For iTunes versions prior to 12.6 on Windows, update to version 12.6 or later.
For tvOS versions prior to 10.2, update to version 10.2 or later.
As a temporary workaround, consider restricting access to the WebKit component until a patch is available. Avoid using the vulnerable component to minimize the risk of exploitation.
