CVSS: 7.5EPSS: 0%CPEs: 67EXPL: 1CVE-2021-23840 – Integer overflow in CipherUpdate
https://notcve.org/view.php?id=CVE-2021-23840
16 Feb 2021 — Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate 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 success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrad... • https://github.com/Trinadh465/openssl-1.1.1g_CVE-2021-23840 • CWE-190: Integer Overflow or Wraparound •

09 Dec 2020 — A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions.

https://notcve.org/view.php?id=CVE-2020-1968
09 Sep 2020 — 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 communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ... • https://lists.debian.org/debian-lts-announce/2020/09/msg00016.html • CWE-203: Observable Discrepancy •

16 Jan 2019 — An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred.

https://notcve.org/view.php?id=CVE-2019-6111
16 Jan 2019 — An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well... • https://packetstorm.news/files/id/151227 • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

10 Jan 2019 — In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. En OpenSSH 7.9, scp.c en el cliente scp permite que los servidores SSH omitan las restricciones de acceso planeadas mediante un nombre de archivo "." o un nombre de archivo vacío.
