The remote NewStart CGSL host, running version MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - It was found that the timer functionality in the Linux     kernel ALSA subsystem is prone to a race condition     between read and ioctl system call handlers, resulting     in an uninitialized memory disclosure to user space. A     local user could use this flaw to read information     belonging to other users. (CVE-2017-1000380)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5715 triggers the     speculative execution by utilizing branch target     injection. It relies on the presence of a precisely-     defined instruction sequence in the privileged code as     well as the fact that memory accesses may cause     allocation into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to cross the syscall and guest/host     boundaries and read privileged memory by conducting     targeted cache side-channel attacks. (CVE-2017-5715)

There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5753 triggers the     speculative execution by performing a bounds-check     bypass. It relies on the presence of a precisely-defined     instruction sequence in the privileged code as well as     the fact that memory accesses may cause allocation into     the microprocessor's data cache even for speculatively     executed instructions that never actually commit     (retire).

There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5754 relies on the     fact that, on impacted microprocessors, during     speculative execution of instruction permission faults,     exception generation triggered by a faulting access is     suppressed until the retirement of the whole instruction     block. In a combination with the fact that memory     accesses may populate the cache even when the block is     being dropped and never committed (executed), an     unprivileged local attacker could use this flaw to read     privileged (kernel space) memory by conducting targeted     cache side-channel attacks. Note: CVE-2017-5754 affects     Intel x86-64 microprocessors. AMD x86-64 microprocessors     are not affected by this issue. (CVE-2017-5754)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
