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-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-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-2019-13050 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-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-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.
CVE-2015-1606 2 Debian, Gnupg 2 Debian Linux, Gnupg 2019-11-22 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-2015-1607 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2019-11-22 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-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-2014-4617 3 Debian, Gnupg, Opensuse 3 Debian Linux, Gnupg, Opensuse 2018-10-30 5.0 MEDIUM N/A
The do_uncompress function in g10/compress.c in GnuPG 1.x before 1.4.17 and 2.x before 2.0.24 allows context-dependent attackers to cause a denial of service (infinite loop) via malformed compressed packets, as demonstrated by an a3 01 5b ff byte sequence.
CVE-2013-4242 4 Canonical, Debian, Gnupg and 1 more 5 Ubuntu Linux, Debian Linux, Gnupg and 2 more 2018-10-30 1.9 LOW N/A
GnuPG before 1.4.14, and Libgcrypt before 1.5.3 as used in GnuPG 2.0.x and possibly other products, allows local users to obtain private RSA keys via a cache side-channel attack involving the L3 cache, aka Flush+Reload.
