Recent Gnupg Security Vulnerabilities

GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached

CVE-2022-3219 3.3 - Low - February 23, 2023

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.

Memory Corruption

A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser

CVE-2022-3515 9.8 - Critical - January 12, 2023

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.

GnuPG through 2.3.6, in unusual situations where an attacker possesses any secret-key information

CVE-2022-34903 6.5 - Medium - July 01, 2022

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.

Injection

A flaw was found in the way certificate signatures could be forged using collisions found in the SHA-1 algorithm

CVE-2019-14855 7.5 - High - March 20, 2020

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.

Inadequate Encryption Strength

Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network

CVE-2019-13050 7.5 - High - June 29, 2019

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.

Improper Certificate Validation

GnuPG version 2.1.12 - 2.2.11 contains a Cross ite Request Forgery (CSRF) vulnerability in dirmngr

CVE-2018-1000858 8.8 - High - December 20, 2018

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.

Session Riding

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

CVE-2018-12020 7.5 - High - June 08, 2018

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.

Use of Incorrectly-Resolved Name or Reference

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

CVE-2018-9234 7.5 - High - April 04, 2018

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.

Key Management Errors

Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG

CVE-2014-9087 - December 01, 2014

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.

Integer underflow

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

CVE-2012-6085 - January 24, 2013

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.

Improper Input Validation

Use-after-free vulnerability in kbx/keybox-blob.c in GPGSM in GnuPG 2.x through 2.0.16

CVE-2010-2547 8.1 - High - August 05, 2010

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.
