CVE-2018-0495 5 Canonical, Debian, Gnupg and 2 more 8 Ubuntu Linux, Debian Linux, Libgcrypt and 5 more 2024-02-28 1.9 LOW 4.7 MEDIUM
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
CVE-2018-12020 4 Canonical, Debian, Gnupg and 1 more 9 Ubuntu Linux, Debian Linux, Gnupg and 6 more 2024-02-28 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-2017-9526 1 Gnupg 1 Libgcrypt 2024-02-28 4.3 MEDIUM 5.9 MEDIUM
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. 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-2017-0379 2 Debian, Gnupg 2 Debian Linux, Libgcrypt 2024-02-28 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.
CVE-2016-6313 3 Canonical, Debian, Gnupg 4 Ubuntu Linux, Debian Linux, Gnupg and 1 more 2024-02-28 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2016-4354 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-02-28 5.0 MEDIUM 7.5 HIGH
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.
CVE-2015-7511 3 Canonical, Debian, Gnupg 3 Ubuntu Linux, Debian Linux, Libgcrypt 2024-02-28 1.9 LOW 2.0 LOW
Libgcrypt before 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations.
CVE-2016-4356 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-02-28 5.0 MEDIUM 7.5 HIGH
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.
CVE-2016-4353 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-02-28 5.0 MEDIUM 7.5 HIGH
ber-decoder.c in Libksba before 1.3.3 does not properly handle decoder stack overflows, which allows remote attackers to cause a denial of service (abort) via crafted BER data.
CVE-2016-4355 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-02-28 5.0 MEDIUM 7.5 HIGH
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.
CVE-2016-4579 3 Canonical, Gnupg, Opensuse 3 Ubuntu Linux, Libksba, Leap 2024-02-28 5.0 MEDIUM 7.5 HIGH
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."
CVE-2016-4574 3 Canonical, Gnupg, Opensuse 4 Ubuntu Linux, Libksba, Leap and 1 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-4356.
CVE-2014-5270 2 Debian, Gnupg 2 Debian Linux, Libgcrypt 2024-02-28 2.1 LOW N/A
Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate attackers to conduct key-extraction attacks by leveraging the ability to collect voltage data from exposed metal, a different vector than CVE-2013-4576.
CVE-2014-4617 3 Debian, Gnupg, Opensuse 3 Debian Linux, Gnupg, Opensuse 2024-02-28 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-2014-9087 4 Canonical, Debian, Gnupg and 1 more 5 Ubuntu Linux, Debian Linux, Gnupg and 2 more 2024-02-28 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-2013-4576 1 Gnupg 1 Gnupg 2024-02-28 2.1 LOW N/A
GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not typically expected to protect themselves from acoustic side-channel attacks, since this is arguably the responsibility of the physical device. Accordingly, issues of this type would not normally receive a CVE identifier. However, for this issue, the developer has specified a security policy in which GnuPG should offer side-channel resistance, and developer-specified security-policy violations are within the scope of CVE.
CVE-2013-4402 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2024-02-28 5.0 MEDIUM N/A
The compressed packet parser in GnuPG 1.4.x before 1.4.15 and 2.0.x before 2.0.22 allows remote attackers to cause a denial of service (infinite recursion) via a crafted OpenPGP message.
CVE-2013-4351 1 Gnupg 1 Gnupg 2024-02-28 5.8 MEDIUM N/A
GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all bits cleared (no usage permitted) as if it has all bits set (all usage permitted), which might allow remote attackers to bypass intended cryptographic protection mechanisms by leveraging the subkey.
CVE-2012-6085 1 Gnupg 1 Gnupg 2024-02-28 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-2013-4242 4 Canonical, Debian, Gnupg and 1 more 5 Ubuntu Linux, Debian Linux, Gnupg and 2 more 2024-02-28 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.
