CVSS: 5.9EPSS: 0%CPEs: 38EXPL: 2CVE-2021-23841 – Null pointer deref in X509_issuer_and_serial_hash()
https://notcve.org/view.php?id=CVE-2021-23841
16 Feb 2021 — The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never di... • https://github.com/Trinadh465/external_boringssl_openssl_1.1.0g_CVE-2021-23841 • CWE-476: NULL Pointer Dereference •

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 •

19 Jan 2021 — Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param.

08 Dec 2020 — The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 • CWE-476: NULL Pointer Dereference •
