CVE-2016-5142 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.68% chance of exploitation in the next 30 days.
