Detailsinfo

A vulnerability was found in Google Chrome 34.0.1847.115 (Web Browser). It has been classified as critical. This affects the function base64decodeinternal of the file wtf/text/base64.cpp of the component Windows Property Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The base64DecodeInternal function in wtf/text/Base64.cpp in Blink, as used in Google Chrome before 34.0.1847.116, does not properly handle string data composed exclusively of whitespace characters, which allows remote attackers to cause a denial of service (out-of-bounds read) via a window.atob method call.
