CVE-2020-12402
During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secr...

EulerOS 2.0 SP5 : libgcrypt (EulerOS-SA-2019-2695)
According to the version of the libgcrypt packages installed, the EulerOS installation on the remote host is affected by the following vulnerability : - Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate...
Side Channel Attack
libgcrypt.so is vulnerable to side-channel attack. The vulnerability exists as the library fails to perform ciphertext blinding for the Elgamal decryption, allowing a local attacker to compromise the server's private key through a crafted ciphertext and analyzing the fluctuations in the...
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...

Side-Channel PoC Attack Lifts Private RSA Keys from Mobile Phones
Researchers have developed a proof-of-concept side-channel attack that allows them to pull encryption keys from a single decryption for a modern version of OpenSSL. The attack impacts mobile devices — without physical access to the handsets. A group of researchers at Georgia Tech were able to...
Side-Channel Attack
libgcrypt.so is vulnerable to side-channel attacks. The elliptic-point curve multiplication during decryption is not properly performed, which allows attackers within close proximity to extract the secret decryption key within seconds by measuring electromagnetic emanations...
Hackers Can Now Steal Data Even From Faraday Cage Air-Gapped Computers
A team of security researchers—which majorly focuses on finding clever ways to get into air-gapped computers by exploiting little-noticed emissions of a computer's components like light, sound and heat—have published another research showcasing that they can steal data not only from an air gap...
How to Leak Data From Air Gapped Computers With USB Devices
Researchers at Ben-Gurion University of Negev have found a way to take a run-of-the-mill USB device and use it to leak data from an air-gapped computers via RF signals. Academics with the school’s Cyber Security Research Labs division claim they’ve come up with software, dubbed USBee, that can...

libgcrypt: secret key extraction
A vulnerability was found in a way the ECDH encryption algorithm decrypts data. An attacker with a specialized setup can extract the secret decryption key from a target located in an adjacent room within seconds. This is done by measuring the target's electromagnetic emanations...
