VCID-4s5w-7qf5-aaak
Aliases: CVE-2015-0837 |
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." |
Affected by 5 other vulnerabilities. |

VCID-av6f-h7c6-aaaq
Aliases: CVE-2017-9526 |
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. |
Affected by 2 other vulnerabilities. |

VCID-d91d-8t7r-aaag
Aliases: CVE-2018-0495 |
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. |
Affected by 0 other vulnerabilities. |

VCID-fan4-zdcw-aaam
Aliases: CVE-2016-6313 |
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. |
Affected by 2 other vulnerabilities. |
|
VCID-ke9d-zyem-aaar
Aliases: CVE-2015-7511 |
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. |
Affected by 4 other vulnerabilities. |
|
VCID-sjza-hk7v-aaag
Aliases: CVE-2014-5270 |
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. |
Affected by 7 other vulnerabilities. |

VCID-vavn-12uu-aaan
Aliases: CVE-2017-7526 |
libgcrypt 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. |
Affected by 1 other vulnerability. |

VCID-vx9d-bz2m-aaan
Aliases: CVE-2014-3591 |
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. |
Affected by 5 other vulnerabilities. |
