Fixes the following security issues:
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.
Incorrect CRYPTO_memcmp on HP-UX PA-RISC (CVE-2018-0733)
Because of an implementation bug the PA-RISC CRYPTO_memcmp function is
effectively reduced to only comparing the least significant bit of each
byte. This allows an attacker to forge messages that would be considered as
authenticated in an amount of tries lower than that guaranteed by the
security claims of the scheme. The module can only be compiled by the HP-UX
assembler, so that only HP-UX PA-RISC targets are affected.
rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
This issue has been reported in a previous OpenSSL security advisory and a
fix was provided for OpenSSL 1.0.2. Due to the low severity no fix was
released at that time for OpenSSL 1.1.0. The fix is now available in
OpenSSL 1.1.0h.
There is an overflow bug in the AVX2 Montgomery multiplication procedure
used in exponentiation with 1024-bit moduli. No EC algorithms are affected.
Analysis suggests that attacks against RSA and DSA as a result of this
defect would be very difficult to perform and are not believed likely.
Attacks against DH1024 are considered just feasible, because most of the
work necessary to deduce information about a private key may be performed
offline. The amount of resources required for such an attack would be
significant. However, for an attack on TLS to be meaningful, the server
would have to share the DH1024 private key among multiple clients, which is
no longer an option since CVE-2016-0701.
This only affects processors that support the AVX2 but not ADX extensions
like Intel Haswell (4th generation).
