CVE-2019-20399

A timing vulnerability in the Scalar::checkoverflow function in Parity libsecp256k1-rs before 0.3.1 potentially allows an attacker to leak information via a side-channel attack...

Kernel: page cache side channel attacks

A new software page cache side channel attack scenario was discovered in operating systems that implement the very common 'page cache' caching mechanism. A malicious user/process could use 'in memory' page-cache knowledge to infer access timings to shared memory and gain knowledge which can be us...

hw: TSX Transaction Asynchronous Abort (TAA)

A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort TAA error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow...

Security Advisory - Page-Cache Side-Channel Vulnerability

There is a vlunerability in the mincore implementation in mm/mincore.c in the Linux kernel through 4.19.13. An attacker could exploit this vulnerability to conduct a page-cache side-channel attack, allowing the attacker to view page-cache access patterns of other processes on the system. A...

Oracle MySQL Connectors OpenSSL (Jan 2020 CPU)

The version of Oracle MySQL Connectors installed on the remote host is 8.0.x prior to 8.0.19 or 5.3.x prior to 5.3.14. It is, therefore, affected by a vulnerability in OpenSSL as noted in the January 2020 Critical Patch Update advisory. This vulnerability is due to a susceptibility to side-channe...

arm: a CPU may speculate past the ERET instruction

ISSUE DESCRIPTION Some CPUs can speculate past an ERET instruction and potentially perform speculative accesses to memory before processing the exception return. Since the register state is often controlled by lower privilege level i.e guest kernel/userspace at the point of the ERET, this could...

SUSE-SU-2020:0099-1 Security update for openssl-1_1

This update for openssl-11 fixes the following issues: Security issue fixed: - CVE-2019-1551: Fixed an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli bsc1158809. - CVE-2019-1563: Fixed bleichenbacher attack against cms/pkcs7 encryptioon...

CVE-2018-5407

A microprocessor side-channel vulnerability was found on SMT e.g, Hyper-Threading architectures. An attacker running a malicious process on the same core of the processor as the victim process can extract certain secret information. Mitigation At this time Red Hat Engineering is working on patche...
