OpenSSL -- multiple vulnerabilities

The OpenSSL project reports:

Constructed ASN.1 types with a recursive definition could
exceed the stack (CVE-2018-0739)
Constructed ASN.1 types with a recursive definition (such as can be
found in PKCS7) could eventually exceed the stack given malicious input
with excessive recursion. This could result in a Denial Of Service
attack. There are no such structures used within SSL/TLS that come from
untrusted sources so this is considered safe.
rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
There is an overflow bug in the AVX2 Montgomery multiplication
procedure used in exponentiation with 1024-bit moduli. This only
affects processors that support the AVX2 but not ADX extensions
like Intel Haswell (4th generation).
