CVE-2022-23960

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. Then, cache allocation can allow the attacker to obtai...

Vulnerability fixed in ARM, AMD and Intel processors

Researchers at VU Amsterdam have found a new variant of the Spectre vulnerability. The researchers have dubbed the attack Branch History Injection. Previous mitigation for Spectre v2 is not sufficient to fully fix the vulnerability, according to the researchers. According to the researchers, this...

Xen Speculative Side Channel Information Disclosure (XSA-320)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by an issue. Incomplete cleanup from specific special register read operations in some IntelR Processors may allow an authenticated user to potentially enable information disclosure via loca...

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...

CVE-2020-1643

Execution of the "show ospf interface extensive" or "show ospf interface detail" CLI commands on a Juniper Networks device running Junos OS may cause the routing protocols process RPD to crash and restart if OSPF interface authentication is configured, leading to a Denial of Service DoS. By...

Authentication flaw

Execution of the "show ospf interface extensive" or "show ospf interface detail" CLI commands on a Juniper Networks device running Junos OS may cause the routing protocols process RPD to crash and restart if OSPF interface authentication is configured, leading to a Denial of Service DoS. By...

Xen Project Denial of Service (XSA-295)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by multiple denial of service DoS vulnerabilities : - A denial of service DoS vulnerability exists in the LoadExcl and StoreExcl operations due to a possible infinite loop. An unauthenticate...
