SUSE SLES15 Security Update : kernel (SUSE-SU-2022:2376-1)

The remote SUSE Linux SLES15 / SLESSAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2376-1 advisory. - Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage...

Xen PV Guest Non-SELFSNOOP CPU Memory Corruption

Xen: PV guest on non-SELFSNOOP CPUs can validate non-coherent L2 pagetable I'm not sure whether there are any major users of unshimmed Xen PV left, but https://xenbits.xen.org/docs/unstable/support-matrix.html says it's still a security-supported usecase for 64-bit guests. Tested on Debian's Xen...

RUSTSEC-2022-0033 Heap memory corruption with RSA private key operation

The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X8664 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a...

Vulnerability in OpenSSL - Heap memory corruption with RSA private key operation

GSD-2022-2274 heap buffer overflow in OpenSSL version 3.0.4

In OpenSSL version 3.0.4 a heap buffer overflow exists in the AVX512 support that can be attacked via network resulting in code execution. This is reachable via four code paths: RSAZ 1024, RSAZ 512, Dual 1024 RSAZ, and Default constant-time Montgomery modular exponentiation. Please note this issu...

Citrix Hypervisor Security Update

A security issue has been identified in Citrix Hypervisor 7.1 LTSR CU2 that may allow privileged code in a PV guest VM to compromise the host. Citrix believes that there would be significant complexity in performing this attack in Citrix Hypervisor. The issue has the following CVE identifier:...

Hertzbleed: A New Side-Channel Attack

Hertzbleed is a new side-channel attack that works against a variety of microprocressors. Deducing cryptographic keys by analyzing power consumption has long been an attack, but its not generally viable because measuring power consumption is often hard. This new attack measures power consumption ...

Miscomputed sha2 results when using AVX2 backend

The v0.9.7 release of the sha2 crate introduced a new AVX2-accelerated backend which was automatically enabled for all x86/x8664 CPUs where AVX2 support was autodetected at runtime. This backend was buggy and would miscompute results for long messages i.e. messages spanning multiple SHA blocks. T...

Hertzbleed exposes computers’ secret whispers

Hertzbleed is the name for a vulnerability that can be used to obtain cryptographic keys and other secret data from Intel and AMD CPUs, remotely. It works by monitoring changes in power consumption, which can be deduced by the careful timing of known workloads, thanks to a processor power saving...
