F5 Networks BIG-IP : RetBleed CPU vulnerability (K83713003)

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K83713003 advisory. - Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29901) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
