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...

CVE-2019-11743

Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history throu...

Security vulnerabilities fixed in Firefox ESR 60.9 — Mozilla

A use-after-free vulnerability can occur while manipulating video elements if the body is freed while still in use. This results in a potentially exploitable crash. Some HTML elements, such as and , can contain literal angle brackets without treating them as markup. It is possible to pass a liter...

hardware: Micro-architectural Load Port Data Sampling - Information Leak (MLPDS)

Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results ar...
