Description
The Web Cryptography API (aka WebCrypto) implementation in Blink, as used in Google Chrome before 52.0.2743.116, does not properly copy data buffers, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted JavaScript code, related to NormalizeAlgorithm.cpp and SubtleCrypto.cpp.
