| CVE | Vendors | Products | Updated | CVSS v2 | CVSS v3 |
|---|---|---|---|---|---|
| CVE-2021-33560 | 4 Debian, Fedoraproject, Gnupg and 1 more | 8 Debian Linux, Fedora, Libgcrypt and 5 more | 2022-07-25 | 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-2021-3345 | 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 | 2021-12-28 | 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-2019-14855 | 3 Canonical, Fedoraproject, Gnupg | 3 Ubuntu Linux, Fedora, Gnupg | 2021-10-29 | 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-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-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-2020-8945 | 3 Fedoraproject, Gnupg, Redhat | 3 Fedora, Gpgme, Openshift Container Platform | 2020-07-24 | 5.1 MEDIUM | 7.5 HIGH |
| The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification. | |||||
| 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-2018-9234 | 2 Canonical, Gnupg | 2 Ubuntu Linux, Gnupg | 2019-02-27 | 5.0 MEDIUM | 7.5 HIGH |
| GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey. | |||||
| CVE-2018-1000858 | 2 Canonical, Gnupg | 2 Ubuntu Linux, Gnupg | 2019-02-13 | 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-2017-0379 | 2 Debian, Gnupg | 2 Debian Linux, Libgcrypt | 2019-01-16 | 5.0 MEDIUM | 7.5 HIGH |
| Libgcrypt before 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for attackers to discover a secret key, related to cipher/ecc.c and mpi/ec.c. | |||||
