Brute-force Attack

kernel is vulnerable to brute-force attacks. The vulnerability exists as bluetooth BR/EDR up to version 5.1 allows sufficiently low encryption key length and also allows an attacker to select a key length during negotiation...

RHEL 7 : kernel (RHSA-2019:2975)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:2975 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: hardware: bluetooth: BR/EDR encryption...

CVE-2016-7055

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...

Bluetooth BR/EDR supported devices are vulnerable to key negotiation attacks

Overview The encryption key length negotiation process in Bluetooth BR/EDR Core v5.1 and earlier is vulnerable to packet injection by an unauthenticated, adjacent attacker that could result in information disclosure and/or escalation of privileges. This can be achieved using an attack referred to...
