| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-01-26 | CVE-2024-0727 | Unspecified vulnerability in Openssl Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a potential Denial of Service attack Impact summary: Applications loading files in the PKCS12 format from untrusted sources might terminate abruptly. A file in PKCS12 format can contain certificates and keys and may come from an untrusted source. | 5.5 |
| 2024-01-09 | CVE-2023-6129 | Out-of-bounds Write vulnerability in Openssl Issue summary: The POLY1305 MAC (message authentication code) implementation contains a bug that might corrupt the internal state of applications running on PowerPC CPU based platforms if the CPU provides vector instructions. Impact summary: If an attacker can influence whether the POLY1305 MAC algorithm is used, the application state might be corrupted with various application dependent consequences. The POLY1305 MAC (message authentication code) implementation in OpenSSL for PowerPC CPUs restores the contents of vector registers in a different order than they are saved. | 6.5 |
| 2023-11-06 | CVE-2023-5678 | Improper Check for Unusual or Exceptional Conditions vulnerability in Openssl Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. | 5.3 |
| 2023-07-31 | CVE-2023-3817 | Excessive Iteration vulnerability in Openssl Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long delays. | 5.3 |
| 2023-07-19 | CVE-2023-3446 | Unspecified vulnerability in Openssl Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long delays. | 5.3 |
| 2023-07-14 | CVE-2023-2975 | Improper Authentication vulnerability in multiple products Issue summary: The AES-SIV cipher implementation contains a bug that causes it to ignore empty associated data entries which are unauthenticated as a consequence. Impact summary: Applications that use the AES-SIV algorithm and want to authenticate empty data entries as associated data can be misled by removing, adding or reordering such empty entries as these are ignored by the OpenSSL implementation. | 5.3 |
| 2023-05-30 | CVE-2023-2650 | Allocation of Resources Without Limits or Throttling vulnerability in multiple products Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be very slow. Impact summary: Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience notable to very long delays when processing those messages, which may lead to a Denial of Service. An OBJECT IDENTIFIER is composed of a series of numbers - sub-identifiers - most of which have no size limit. | 6.5 |
| 2023-04-20 | CVE-2023-1255 | Out-of-bounds Read vulnerability in Openssl 3.0.0/3.1.0/3.1.1 Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that could cause it to read past the input buffer, leading to a crash. Impact summary: Applications that use the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. | 5.9 |
| 2023-03-28 | CVE-2023-0465 | Improper Certificate Validation vulnerability in Openssl Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. | 5.3 |
| 2023-03-28 | CVE-2023-0466 | Improper Certificate Validation vulnerability in Openssl The function X509_VERIFY_PARAM_add0_policy() is documented to implicitly enable the certificate policy check when doing certificate verification. | 5.3 |
