15 Sep 2021 — 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.

15 Sep 2021 — When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.

CVE-2021-22946 – curl: Requirement to use TLS not properly enforced for IMAP, POP3, and FTP protocols
https://notcve.org/view.php?id=CVE-2021-22946
15 Sep 2021 — A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitiv... • http://seclists.org/fulldisclosure/2022/Mar/29 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •

CVE-2021-22947 – curl: Server responses received before STARTTLS processed after TLS handshake
https://notcve.org/view.php?id=CVE-2021-22947
15 Sep 2021 — When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-thro... • http://seclists.org/fulldisclosure/2022/Mar/29 • CWE-310: Cryptographic Issues CWE-319: Cleartext Transmission of Sensitive Information CWE-345: Insufficient Verification of Data Authenticity •

CVE-2021-3711 – SM2 Decryption Buffer Overflow
https://notcve.org/view.php?id=CVE-2021-3711
24 Aug 2021 — In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). 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 required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the "out" parameter.
