https://notcve.org/view.php?id=CVE-2017-3738
07 Dec 2017 — 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 sign... • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html • CWE-190: Integer Overflow or Wraparound CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.9EPSS: 22%CPEs: 13EXPL: 0CVE-2017-3737 – openssl: Read/write after SSL object in error state
https://notcve.org/view.php?id=CVE-2017-3737
07 Dec 2017 — OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake f... • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html • CWE-125: Out-of-bounds Read CWE-391: Unchecked Error Condition CWE-787: Out-of-bounds Write •

02 Nov 2017 — There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. 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.

https://notcve.org/view.php?id=CVE-2017-3735
28 Aug 2017 — While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread. This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. Al analizar una extensión IPAddressFamily en un certificado X.509, es posible realizar una sobrelectura de un bit. Esto tendría como resultado que el texto del certificado se muestre de forma incorrecta. • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

16 Feb 2017 — During a renegotiation handshake if the Encrypt-Then-Mac extension is negotiated where it was not in the original handshake (or vice-versa) then this can cause OpenSSL 1.1.0 before 1.1.0e to crash (dependent on ciphersuite). Both clients and servers are affected.

26 Jan 2017 — In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack.

26 Jan 2017 — If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to 1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that algorithm should update to 1.0.2k.
