CVE-2010-2547Hig0.548.10.15Aug 5, 2010Use-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-2016-4356Hig0.497.50.01Jun 13, 2016The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attackers to cause a denial of service (out-of-bounds read) by clearing the high bit of the byte after invalid utf-8 encoded data.
CVE-2016-4355Hig0.497.50.01Jun 13, 2016Multiple integer overflows in ber-decoder.c in Libksba before 1.3.3 allow remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.
CVE-2016-4354Hig0.497.50.01Jun 13, 2016ber-decoder.c in Libksba before 1.3.3 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.
CVE-2026-41989Med0.446.70.00Apr 23, 2026Libgcrypt before 1.12.2 sometimes allows a heap-based buffer overflow and denial of service via crafted ECDH ciphertext to gcry_pk_decrypt.
CVE-2017-9526Med0.385.90.01Jun 11, 2017In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.
CVE-2016-6313Med0.355.30.03Dec 13, 2016The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.
CVE-2026-41990Med0.264.00.00Apr 23, 2026Libgcrypt before 1.12.2 mishandles Dilithium signing. Writes to a static array lack a bounds check but do not use attacker-controlled data.
CVE-2006-37460.06—0.35Jul 28, 2006Integer overflow in parse_comment in GnuPG (gpg) 1.4.4 allows remote attackers to cause a denial of service (segmentation fault) via a crafted message.
CVE-2007-12630.05—0.25Mar 6, 2007GnuPG 1.4.6 and earlier and GPGME before 1.1.4, when run from the command line, does not visually distinguish signed and unsigned portions of OpenPGP messages with multiple components, which might allow remote attackers to forge the contents of a message without detection.
CVE-2006-30820.05—0.30Jun 19, 2006parse-packet.c in GnuPG (gpg) 1.4.3 and 1.9.20, and earlier versions, allows remote attackers to cause a denial of service (gpg crash) and possibly overwrite memory via a message packet with a large length (long user ID string), which could lead to an integer overflow, as demonstrated using the --no-armor option.
CVE-2014-46170.01—0.08Jun 25, 2014The 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-2005-03660.01—0.08May 2, 2005The 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-2026-248830.00—0.00Jan 27, 2026In GnuPG before 2.5.17, a long signature packet length causes parse_signature to return success with sig->data[] set to a NULL value, leading to a denial of service (application crash).
CVE-2026-248820.00—0.00Jan 27, 2026In GnuPG before 2.5.17, a stack-based buffer overflow exists in tpm2daemon during handling of the PKDECRYPT command for TPM-backed RSA and ECC keys.
CVE-2026-248810.00—0.00Jan 27, 2026In GnuPG before 2.5.17, a crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling. This can easily be leveraged for denial of service; however, there is also memory corruption that could lead to remote code execution.
CVE-2025-689720.00—0.00Dec 27, 2025In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.
CVE-2025-302580.00—0.00Mar 19, 2025In GnuPG before 2.5.5, if a user chooses to import a certificate with certain crafted subkey data that lacks a valid backsig or that has incorrect usage flags, the user loses the ability to verify signatures made from certain other signing keys, aka a "verification DoS."
CVE-2017-75260.00—0.03Jul 26, 2018libgcrypt 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-2014-90870.00—0.04Dec 1, 2014Integer 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.
