Detailsinfo

A vulnerability classified as critical has been found in Apple iOS up to 9.2 (Smartphone Operating System). This affects an unknown code block of the component WebKit. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

WebKit in Apple iOS before 9.3, Safari before 9.1, and tvOS before 9.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site.
