kernel: hw: Spectre SWAPGS gadget vulnerability

A Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel...

Intel CPUs Vulnerable to Sensitive Data Leakage in NetCAT Attack

Researchers have identified a new side-channel attack impacting all modern Intel server processors made since 2012. The vulnerability could allow bad actors to sniff out encrypted passwords as they are being typed into a secure shell session SSH; but, luckily, such an attack would be difficult to...

NetCAT: New Attack Lets Hackers Remotely Steal Data From Intel CPUs

Unlike previous side-channel vulnerabilities disclosed in Intel CPUs, researchers have discovered a new flaw that can be exploited remotely over the network without requiring an attacker to have physical access or any malware installed on a targeted computer. Dubbed NetCAT, short for Network Cach...

Side-Channel Attack

openssl is vulnerable to side channel attacks. The library falls back to non-side channel resistant code paths when an OpenSSL EC group is constructed without a cofactor present, using explicit parameters instead of a named curve. This can result in the recovery of the full key during an ECDSA...

Cross Origin Access

firefox is vulnerable to cross-origin access. The vulnerability exists due to not the adhering to the W3C's Navigation-Timing Level 2 which allows an attacker to do potential cross-origin information exposure of history via timing side-channel attacks...

ALPINE-CVE-2019-1547

Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a group does not have...

Mbed TLS -- Side channel attack on deterministic ECDSA

Janos Follath reports: Mbed TLS does not have a constant-time/constant-trace arithmetic library and uses blinding to protect against side channel attacks. In the ECDSA signature routine previous Mbed TLS versions used the same RNG object for generating the ephemeral key pair and for generating th...

OpenSSL Vulnerabilities Oct 2018 - Jul 2019

SUMMARY Symantec Network Protection products using affected versions of OpenSSL are susceptible to multiple vulnerabilities. An attacker can recover DSA, ECDH, and ECDSA private keys through timing side-channel attacks. A remote attacker can also decrypt encrypted ciphertext and modify OpenSSL...
