CVE-2016-20012

OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE...

Botan 加密问题漏洞

Botan is a library of cryptographic algorithms written in C++. It supports a variety of algorithms such as AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability exists in Botan 2.18.1 and earlier versions, which stems from the fact that a generator public key defined by the...

scalarmult() vulnerable to degenerate public keys

The scalarmult function included in previous versions of this crate accepted all-zero public keys, for which the resulting Diffie-Hellman shared secret will always be zero regardless of the private key used. This issue was fixed by checking for this class of keys and rejecting them if they are us...

ALPINE-CVE-2021-3711

In order to decrypt SM2 encrypted data an application is expected to call the API function EVPPKEYdecrypt. Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with the buffer size...
