David Benjamin 2a19a17ca7 Limit ASN.1 constructed types recursive definition depth
Constructed types with a recursive definition could eventually exceed
the stack given malicious input with excessive recursion. Therefore we
limit the stack depth.

CVE-2018-0739

Credit to OSSFuzz for finding this issue.

(Imported from upstream's 9310d45087ae546e27e61ddf8f6367f29848220d.)

BoringSSL does not contain any such structures, but import this anyway
with a test.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
