DATE CVE VULNERABILITY TITLE RISK
2018-04-04 CVE-2018-9234 Key Management Errors vulnerability in multiple products
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.
network
low complexity
gnupg canonical CWE-320
7.5
2018-02-07 CVE-2018-6829 Use of a Broken or Risky Cryptographic Algorithm vulnerability in Gnupg Libgcrypt
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).
network
low complexity
gnupg CWE-327
7.5
2017-08-29 CVE-2017-0379 Information Exposure vulnerability in multiple products
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.
network
low complexity
gnupg debian CWE-200
7.5
2017-06-11 CVE-2017-9526 Information Exposure vulnerability in Gnupg Libgcrypt
In 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.
network
high complexity
gnupg CWE-200
5.9
2016-12-13 CVE-2016-6313 Information Exposure vulnerability in multiple products
The 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.

gnupg debian canonical CWE-200
5.3
2016-06-13 CVE-2016-4579 Improper Input Validation vulnerability in multiple products
Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via unspecified vectors, related to the "returned length of the object from _ksba_ber_parse_tl."

gnupg opensuse canonical CWE-20
7.5
2016-06-13 CVE-2016-4574 Numeric Errors vulnerability in multiple products
Off-by-one error in the append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read) via invalid utf-8 encoded data.
network
low complexity
gnupg canonical opensuse CWE-189
7.5
2016-06-13 CVE-2016-4356 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
The 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.
network
low complexity
gnupg canonical CWE-119
7.5
2016-06-13 CVE-2016-4355 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Multiple 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.

2016-06-13 CVE-2016-4354 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
ber-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.
