|---|---|---|---|---|---|
| CVE-2019-12904 | 2 Gnupg, Opensuse | 2 Libgcrypt, Leap | 2024-04-11 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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-2010-2547 | 3 Debian, Fedoraproject, Gnupg | 3 Debian Linux, Fedora, Gnupg | 2024-02-02 | 5.1 MEDIUM | 8.1 HIGH |
| 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-2022-3219 | 1 Gnupg | 1 Gnupg | 2023-12-10 | N/A | 3.3 LOW |
| 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-2022-3515 | 2 Gnupg, Gpg4win | 4 Gnupg, Libksba, Vs-desktop and 1 more | 2023-12-10 | 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-2022-47629 | 2 Debian, Gnupg | 2 Debian Linux, Libksba | 2023-12-10 | N/A | 9.8 CRITICAL |
| Libksba before 1.6.3 is prone to an integer overflow vulnerability in the CRL signature parser. | |||||
| CVE-2022-34903 | 4 Debian, Fedoraproject, Gnupg and 1 more | 5 Debian Linux, Fedora, Gnupg and 2 more | 2023-12-10 | 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-2021-33560 | 4 Debian, Fedoraproject, Gnupg and 1 more | 8 Debian Linux, Fedora, Libgcrypt and 5 more | 2023-12-10 | 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-2021-40528 | 1 Gnupg | 1 Libgcrypt | 2023-12-10 | 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-2021-3345 | 2 Gnupg, Oracle | 2 Libgcrypt, Communications Billing And Revenue Management | 2023-12-10 | 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-2020-25125 | 2 Gnupg, Gpg4win | 2 Gnupg, Gpg4win | 2023-12-10 | 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-2019-14855 | 3 Canonical, Fedoraproject, Gnupg | 3 Ubuntu Linux, Fedora, Gnupg | 2023-12-10 | 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-2015-1607 | 2 Canonical, Gnupg | 2 Ubuntu Linux, Gnupg | 2023-12-10 | 4.3 MEDIUM | 5.5 MEDIUM |
| kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x before 2.0.27, and 2.1.x before 2.1.2 does not properly handle bitwise left-shifts, which allows remote attackers to cause a denial of service (invalid read operation) via a crafted keyring file, related to sign extensions and "memcpy with overlapping ranges." | |||||
| CVE-2015-0837 | 2 Debian, Gnupg | 3 Debian Linux, Gnupg, Libgcrypt | 2023-12-10 | 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 | 2023-12-10 | 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 | 2023-12-10 | 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. | |||||
| CVE-2015-1606 | 2 Debian, Gnupg | 2 Debian Linux, Gnupg | 2023-12-10 | 4.3 MEDIUM | 5.5 MEDIUM |
| The keyring DB in GnuPG before 2.1.2 does not properly handle invalid packets, which allows remote attackers to cause a denial of service (invalid read and use-after-free) via a crafted keyring file. | |||||
| CVE-2019-13050 | 5 F5, Fedoraproject, Gnupg and 2 more | 5 Traffix Signaling Delivery Controller, Fedora, Gnupg and 2 more | 2023-12-10 | 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-2018-1000858 | 2 Canonical, Gnupg | 2 Ubuntu Linux, Gnupg | 2023-12-10 | 6.8 MEDIUM | 8.8 HIGH |
| GnuPG version 2.1.12 - 2.2.11 contains a Cross ite Request Forgery (CSRF) vulnerability in dirmngr that can result in Attacker controlled CSRF, Information Disclosure, DoS. This attack appear to be exploitable via Victim must perform a WKD request, e.g. enter an email address in the composer window of Thunderbird/Enigmail. This vulnerability appears to have been fixed in after commit 4a4bb874f63741026bd26264c43bb32b1099f060. | |||||
| CVE-2017-7526 | 3 Canonical, Debian, Gnupg | 3 Ubuntu Linux, Debian Linux, Libgcrypt | 2023-12-10 | 4.3 MEDIUM | 6.8 MEDIUM |
| libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used. | |||||
| CVE-2018-12020 | 4 Canonical, Debian, Gnupg and 1 more | 9 Ubuntu Linux, Debian Linux, Gnupg and 6 more | 2023-12-10 | 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. | |||||
