Information Disclosure

mbedtls is vulnerable to information disclosure. The vulnerability exists as the ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key v...

Oracle Linux 7 : Unbreakable Enterprise kernel (ELSA-2020-5755)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5755 advisory. - p54usb: Fix race between disconnect and firmware loading Alan Stern Orabug: 31351863 CVE-2019-15220 - media: rc: prevent memory leak in cx23888irprob...

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...

According to the versions of the wpasupplicant package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - The implementations of SAE in hostapd and wpasupplicant are vulnerable to side channel attacks as a result of observable...

Another Intel Speculative Execution Vulnerability

Remember Spectre and Meltdown? Back in early 2018, I wrote: Spectre and Meltdown are pretty catastrophic vulnerabilities, but they only affect the confidentiality of data. Now that they -- and the research into the Intel ME vulnerability -- have shown researchers where to look, more is coming --...

Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU's trusted execution environments TEE. Called SGAxe, the first of the flaws is an evolution of the previously uncovered CacheOut attack...

Unpatchable 'Starbleed' Bug in FPGA Chips Exposes Critical Devices to Hackers

A newly discovered unpatchable hardware vulnerability in Xilinx programmable logic products could allow an attacker to break bitstream encryption, and clone intellectual property, change the functionality, and even implant hardware Trojans. The details of the attacks against Xilinx 7-Series and...

CVE-2020-11713

CVE-2020-11713 affects wolfSSL 4.3.0, where mulmod code in wc_ecc_mulmod_ex (ecc.c) does not properly resist timing side‑channel attacks. The vulnerability exposes potential leakage of sensitive information due to timing analysis, with the NVD noting a potentially high impact under CVSSv3 (C: HIG...

CVE-2018-3665

A Floating Point Unit FPU state information leakage flaw was found in the way the Linux kernel saved and restored the FPU state during task switch. Linux kernels that follow the "Lazy FPU Restore" scheme are vulnerable to the FPU state information leakage issue. An unprivileged local attacker cou...

CVE-2019-7308

A bypass was found for the Spectre v1 hardening in the eBPF engine of the Linux kernel. The code in the kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize,...

CVE-2019-18660

A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache indirect branch cache and Link Return Address Stack on the PowerPC platform. The flushing of these structures helps to prevent SpectreRSB like attacks which may leak information from one user process to...
