| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-02-23 | CVE-2022-3219 | Out-of-bounds Write vulnerability in Gnupg GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached, compressed down to just a few KB. | 3.3 |
| 2023-01-12 | CVE-2022-3515 | A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser. | 9.8 |
| 2022-12-20 | CVE-2022-47629 | Integer Overflow or Wraparound vulnerability in multiple products Libksba before 1.6.3 is prone to an integer overflow vulnerability in the CRL signature parser. | 9.8 |
| 2022-07-01 | CVE-2022-34903 | Injection vulnerability in multiple products GnuPG through 2.3.6, in unusual situations where an attacker possesses any secret-key information from a victim's keyring and other constraints (e.g., use of GPGME) are met, allows signature forgery via injection into the status line. | 6.5 |
| 2021-09-06 | CVE-2021-40528 | Use of a Broken or Risky Cryptographic Algorithm vulnerability in Gnupg Libgcrypt The ElGamal implementation in Libgcrypt before 1.9.4 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP. | 5.9 |
| 2021-06-08 | CVE-2021-33560 | Information Exposure Through Discrepancy vulnerability in multiple products Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. | 7.5 |
| 2021-01-29 | CVE-2021-3345 | Out-of-bounds Write vulnerability in multiple products _gcry_md_block_write in cipher/hash-common.c in Libgcrypt version 1.9.0 has a heap-based buffer overflow when the digest final function sets a large count value. | 7.8 |
| 2020-09-03 | CVE-2020-25125 | Classic Buffer Overflow vulnerability in multiple products GnuPG 2.2.21 and 2.2.22 (and Gpg4win 3.1.12) has an array overflow, leading to a crash or possibly unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD preferences. | 7.8 |
| 2020-03-20 | CVE-2019-14855 | Inadequate Encryption Strength vulnerability in multiple products A flaw was found in the way certificate signatures could be forged using collisions found in the SHA-1 algorithm. | 7.5 |
| 2019-11-29 | CVE-2015-0837 | Information Exposure Through Discrepancy vulnerability in multiple products The mpi_powm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack." | 5.9 |
