KB4566782: Windows 10 Version 2004 August 2020 Security Update

The remote Windows host is missing security update 4566782. It is, therefore, affected by multiple vulnerabilities : - A memory corruption vulnerability exists when Windows Media Foundation improperly handles objects in memory. An attacker who successfully exploited the vulnerability could instal...

Name of the Vulnerable Software and Affected Versions: Windows versions prior to the fixed version Description: The issue is related to an information disclosure vulnerability in ARM implementations of Windows, which is connected to the lack of protection for service data. This vulnerability can ...

Intel, ARM, IBM, AMD Processors Vulnerable to New Side-Channel Attacks

It turns out that the root cause behind several previously disclosed speculative execution attacks against modern processors, such as Meltdown and Foreshadow, was misattributed to 'prefetching effect,' resulting in hardware vendors releasing incomplete mitigations and countermeasures. Sharing its...

Information Disclosure

Arm Mbed TLS is vulnerable to Information Disclosure. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side channels in the conversion to...

Denial Of Service (DoS)

Xen is vulnerable to denial of service DoS. Arm guest OS users can cause a hypervisor crash because of a missing alignment check in VCPUOPregistervcpuinfo. The hypercall VCPUOPregistervcpuinfo is used by a guest to register a shared region with the hypervisor. The region will be mapped into Xen...

Sensitive Information Disclosure

Arm Mbed TLS is vulnerable to sensitive information leakage. When deterministic ECDSA is enabled, it uses an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times...

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...

qemu: weak signature generation in Pointer Authentication support for ARM

A flaw was found in QEMU in the implementation of the Pointer Authentication PAuth support for ARM. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer an...

Mozilla: Memory corruption due to missing sign-extension for ValueTags on ARM64
