CVE-2022-3219 | 1 Gnupg | 1 Gnupg | 2023-03-03 | N/A | 5.5 MEDIUM |
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. | |||||
CVE-2012-6085 | 1 Gnupg | 1 Gnupg | 2023-02-12 | 5.8 MEDIUM | N/A |
The read_block function in g10/import.c in GnuPG 1.4.x before 1.4.13 and 2.0.x through 2.0.19, when importing a key, allows remote attackers to corrupt the public keyring database or cause a denial of service (application crash) via a crafted length field of an OpenPGP packet. | |||||
CVE-2010-2547 | 1 Gnupg | 1 Gnupg | 2023-02-12 | 5.1 MEDIUM | N/A |
Use-after-free vulnerability in kbx/keybox-blob.c in GPGSM in GnuPG 2.x through 2.0.16 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a certificate with a large number of Subject Alternate Names, which is not properly handled in a realloc operation when importing the certificate or verifying its signature. | |||||
CVE-2022-3515 | 3 Gnupg, Gpg4win, Libksba Project | 4 Gnupg, Vs-desktop, Gpg4win and 1 more | 2023-01-20 | N/A | 9.8 CRITICAL |
A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser. The vulnerability can be exploited remotely for code execution on the target system by passing specially crafted data to the application, for example, a malicious S/MIME attachment. | |||||
CVE-2021-40528 | 1 Gnupg | 1 Libgcrypt | 2022-12-06 | 2.6 LOW | 5.9 MEDIUM |
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. | |||||
CVE-2021-33560 | 4 Debian, Fedoraproject, Gnupg and 1 more | 8 Debian Linux, Fedora, Libgcrypt and 5 more | 2022-12-06 | 5.0 MEDIUM | 7.5 HIGH |
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. This, for example, affects use of ElGamal in OpenPGP. | |||||
CVE-2019-14855 | 3 Canonical, Fedoraproject, Gnupg | 3 Ubuntu Linux, Fedora, Gnupg | 2022-11-07 | 5.0 MEDIUM | 7.5 HIGH |
A flaw was found in the way certificate signatures could be forged using collisions found in the SHA-1 algorithm. An attacker could use this weakness to create forged certificate signatures. This issue affects GnuPG versions before 2.2.18. | |||||
CVE-2022-34903 | 4 Debian, Fedoraproject, Gnupg and 1 more | 5 Debian Linux, Fedora, Gnupg and 2 more | 2022-09-09 | 5.8 MEDIUM | 6.5 MEDIUM |
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. | |||||
CVE-2021-3345 | 2 Gnupg, Oracle | 2 Libgcrypt, Communications Billing And Revenue Management | 2022-04-26 | 7.2 HIGH | 7.8 HIGH |
_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. It is recommended to upgrade to 1.9.1 or later. | |||||
CVE-2018-12020 | 4 Canonical, Debian, Gnupg and 1 more | 9 Ubuntu Linux, Debian Linux, Gnupg and 6 more | 2022-04-18 | 5.0 MEDIUM | 7.5 HIGH |
mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes. | |||||
CVE-2019-12904 | 2 Gnupg, Opensuse | 2 Libgcrypt, Leap | 2021-07-21 | 4.3 MEDIUM | 5.9 MEDIUM |
** DISPUTED ** In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) NOTE: the vendor's position is that the issue report cannot be validated because there is no description of an attack. | |||||
CVE-2019-13050 | 5 F5, Fedoraproject, Gnupg and 2 more | 5 Traffix Signaling Delivery Controller, Fedora, Gnupg and 2 more | 2021-06-29 | 5.0 MEDIUM | 7.5 HIGH |
Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through 2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS keyserver network. Retrieving data from this network may cause a persistent denial of service, because of a Certificate Spamming Attack. | |||||
CVE-2005-0366 | 1 Gnupg | 1 Gnupg | 2020-12-10 | 5.0 MEDIUM | N/A |
The integrity check feature in OpenPGP, when handling a message that was encrypted using cipher feedback (CFB) mode, allows remote attackers to recover part of the plaintext via a chosen-ciphertext attack when the first 2 bytes of a message block are known, and an oracle or other mechanism is available to determine whether an integrity check failed. | |||||
CVE-2020-25125 | 2 Gnupg, Gpg4win | 2 Gnupg, Gpg4win | 2020-09-11 | 6.8 MEDIUM | 7.8 HIGH |
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. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG 2.2.23 is a fixed version. | |||||
CVE-2018-0495 | 5 Canonical, Debian, Gnupg and 2 more | 8 Ubuntu Linux, Debian Linux, Libgcrypt and 5 more | 2020-08-24 | 1.9 LOW | 4.7 MEDIUM |
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | |||||
CVE-2014-9087 | 5 Canonical, Debian, Gnupg and 2 more | 5 Ubuntu Linux, Debian Linux, Gnupg and 2 more | 2020-07-14 | 7.5 HIGH | N/A |
Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG, allows remote attackers to cause a denial of service (crash) via a crafted OID in a (1) S/MIME message or (2) ECC based OpenPGP data, which triggers a buffer overflow. | |||||
CVE-2018-6829 | 1 Gnupg | 1 Libgcrypt | 2020-01-15 | 5.0 MEDIUM | 7.5 HIGH |
cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for Libgcrypt's ElGamal implementation. | |||||
CVE-2015-0837 | 2 Debian, Gnupg | 3 Debian Linux, Gnupg, Libgcrypt | 2019-12-14 | 4.3 MEDIUM | 5.9 MEDIUM |
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." | |||||
CVE-2011-2207 | 3 Debian, Gnupg, Redhat | 3 Debian Linux, Gnupg, Enterprise Linux | 2019-12-13 | 5.0 MEDIUM | 5.3 MEDIUM |
dirmngr before 2.1.0 improperly handles certain system calls, which allows remote attackers to cause a denial of service (DOS) via a specially-crafted certificate. | |||||
CVE-2014-3591 | 2 Debian, Gnupg | 3 Debian Linux, Gnupg, Libgcrypt | 2019-12-05 | 1.9 LOW | 4.2 MEDIUM |
Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication. |
