CVE-2021-23840

Calls to EVPCipherUpdate, EVPEncryptUpdate and EVPDecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 indicating succes...

DEBIAN-CVE-2020-1968

The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman DH based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted...

openssl: information disclosure in PKCS7_dataDecode and CMS_decrypt_set1_pkey

In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted...

Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.1.1i and below OpenSSL versions 1.0.2x and below Description The issue is related to the functions EVP CipherUpdate, EVP EncryptUpdate, and EVP DecryptUpdate in OpenSSL, which may overflow the output length argument when the...

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...

UBUNTU-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...
