Meltdown -Spectre test results
 
Hi all,
When will this be fixed with Zenwalk?
I like this os
Thanks

Spectre and Meltdown mitigation detection tool v0.35

Checking for vulnerabilities on current system
Kernel is Linux 4.9.67 #2 SMP Tue Dec 5 16:29:07 CST 2017 x86_64
CPU is Intel(R) Core(TM) i5-3340M CPU @ 2.70GHz

Hardware check
* Hardware support (CPU microcode) for mitigation techniques
* Indirect Branch Restricted Speculation (IBRS)
* SPEC_CTRL MSR is available: NO
* CPU indicates IBRS capability: NO
* Indirect Branch Prediction Barrier (IBPB)
* PRED_CMD MSR is available: NO
* CPU indicates IBPB capability: NO
* Single Thread Indirect Branch Predictors (STIBP)
* SPEC_CTRL MSR is available: NO
* CPU indicates STIBP capability: NO
* Enhanced IBRS (IBRS_ALL)
* CPU indicates ARCH_CAPABILITIES MSR availability: NO
* ARCH_CAPABILITIES MSR advertises IBRS_ALL capability: NO
* CPU explicitly indicates not being vulnerable to Meltdown (RDCL_NO): NO
* CPU microcode is known to cause stability problems: NO (model 58 stepping 9 ucode 0x15)
* CPU vulnerability to the three speculative execution attacks variants
* Vulnerable to Variant 1: YES
* Vulnerable to Variant 2: YES
* Vulnerable to Variant 3: YES

CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Kernel has array_index_mask_nospec: NO
* Kernel has the Red Hat/Ubuntu patch: NO
* Checking count of LFENCE instructions following a jump in kernel... NO (only 18 jump-then-lfence instructions found, should be >= 30 (heuristic))
> STATUS: VULNERABLE (Kernel source needs to be patched to mitigate the vulnerability)

CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'
* Mitigation 1
* Kernel is compiled with IBRS/IBPB support: NO
* Currently enabled features
* IBRS enabled for Kernel space: NO
* IBRS enabled for User space: NO
* IBPB enabled: NO
* Mitigation 2
* Kernel compiled with retpoline option: NO
* Kernel compiled with a retpoline-aware compiler: NO
> STATUS: VULNERABLE (IBRS hardware + kernel support OR kernel with retpoline are needed to mitigate the vulnerability)

CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3'
* Kernel supports Page Table Isolation (PTI): NO
* PTI enabled and active: NO
* Running as a Xen PV DomU: NO
> STATUS: VULNERABLE (PTI is needed to mitigate the vulnerability)

A false sense of security is worse than no security at all, see --disclaimer

This is a problem with the CPU.
Bios Update or microcode update.
