ALPINE-CVE-2019-1547

Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a group does not have...

CVE-2019-0223

While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 C library and its language bindings can connect to a peer anonymously using TLS even when configured to verify the peer certificate while used with OpenSSL versions before...

UBUNTU-CVE-2019-1543

ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also...

testssl.sh - Testing TLS/SSL Encryption Anywhere On Any Port

testssl.sh is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as some cryptographic flaws. Key features Clear output: you can tell easily whether anything is good or bad Ease of installation: It works for Linux, OSX/Darwin...

ALPINE-CVE-2018-0733

Because of an implementation bug the PA-RISC CRYPTOmemcmp 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...

Name of the Vulnerable Software and Affected Versions: OpenSSL versions 1.1.1 through 1.1.1j MySQL Server versions 5.7.33 and earlier, 8.0.23 and earlier Description: The issue is related to a NULL pointer dereference in OpenSSL TLS servers when a maliciously crafted renegotiation ClientHello...

ALPINE-CVE-2017-3732

There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. 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...

ALPINE-CVE-2016-2106

Integer overflow in the EVPEncryptUpdate function in crypto/evp/evpenc.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service heap memory corruption via a large amount of data...

OpenSSL Cross-Protocol Attack Vulnerability

OpenSSL is a general-purpose open source cryptographic library that implements Secure Sockets Layer and Secure Transport Layer protocols and can support a variety of cryptographic algorithms, including symmetric ciphers, hashing algorithms, secure hashing algorithms, and so on. Cross-protocol...

UBUNTU-CVE-2015-1791

Race condition in the ssl3getnewsessionticket function in ssl/s3clnt.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b, when used for a multi-threaded client, allows remote attackers to cause a denial of service double free and application crash or...
