Detailsinfo

A vulnerability, which was classified as very critical, was found in Apple iOS up to 6.1.4 (Smartphone Operating System). This affects an unknown function 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:

Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, does not properly implement web audio nodes, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

The weakness was presented 09/18/2013 by Atte Kettunen with OUSPG as APPLE-SA-2013-09-18-2 iOS 7 as confirmed mailinglist post (Website). The advisory is shared at prod.lists.apple.com. The mailinglist post contains:

Multiple memory corruption issues existed in WebKit. These issues were addressed through improved memory handling.
