Invalid Curve Attack in openpgp

Versions of openpgp prior to 4.3.0 are vulnerable to an Invalid Curve Attack. The package's implementation of ECDH fails to verify the validity of the communication partner's public key. The package calculates the resulting key secret based on an altered curve instead of the specified elliptic...

[SECURITY] [DLA 1886-2] openjdk-7 regression update

Package : openjdk-7 Version : 7u231-2.6.19-1deb8u2 Debian Bug : 935082 750400 The latest security update of openjdk-7 caused a regression when applications relied on elliptic curve algorithms to establish SSL connections. Several duplicate classes were removed from rt.jar by the upstream develope...

Debian DLA-1886-2 : openjdk-7 regression update

The latest security update of openjdk-7 caused a regression when applications relied on elliptic curve algorithms to establish SSL connections. Several duplicate classes were removed from rt.jar by the upstream developers of OpenJDK because they were also present in sunec.jar. However Debian neve...

Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-4094-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4094-1 advisory. It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could...

USN-4095-2 linux-lts-xenial, linux-aws vulnerabilities

USN-4095-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement HWE kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 ESM. Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux...

USN-4095-1 linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities

Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux kernel did not properly validate elliptic curve parameters during Diffie-Hellman key exchange in some situations. An attacker could use this to expose sensitive information. CVE-2018-5383 It was discovered that a...

ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries

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 gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

kernel: Bluetooth implementations may not sufficiently validate elliptic curve parameters during Diffie-Hellman key exchange

A vulnerability in Bluetooth pairing potentially allows an attacker with physical proximity within 30 meters to gain unauthorized access via an adjacent network, intercept traffic and send forged pairing messages between two vulnerable Bluetooth devices. This may result in information disclosure,...

nss: Empty or malformed p256-ECDH public keys may trigger a segmentation fault

Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used. This vulnerability affects Firefox ESR 60.8, Firefox 68, and Thunderbird 60.8...

UBUNTU-CVE-2019-14318

Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because scalar multiplication in ecp.cpp...

Side-channel Attack

openjdk is vulnerable to side-channel attack. An unknown difficult to exploit vulnerability allows an unauthenticated attacker with access to gain unauthorizaed access to critical system resources due to security risks arising from using deprecated functions within Elliptic Curve EC cryptography...
