Jan 05, 2018 · Rune dragons are metal dragons first encountered during Dragon Slayer II, in which the player must fight against one during Zorgoth's assault. After completion of the quest, they can be found in the eastern chamber of the Lithkren Vault. To get back to the laboratory underneath Lithkren, players can travel using the rowboat from the quest or, after completion, taking a digsite pendant and ... Oct 10, 2018 · Consider segmentation attacks, for example. In these attacks, one virtual image interacts directly with another on the same hypervisor or otherwise subverts the expected workload boundaries. Cloud customers generally build their security models around the idea that segmentation attacks can't or won't happen and deploy them accordingly.

Jan 19, 2018 · Spectre attacks affect all those manufacturers, plus AMD, plus a variant of the attack also impacted the Mill (a new CPU design so exotic it doesn’t even have registers). That isn’t surprising because CPUs have been speculating past bounds checks and indirect jumps for decades — it’s a basic requirement given that electricity moves at ...

Related topics. There are three more labs related to race condition. One is the Dirty COW attack lab, which exploits a race condition vulnerability inside the OS kernel (Chapter 8 of the SEED book covers this attack). The other two are Meltdown and Spectre attack labs (Chapters 13 and 14 of the SEED book). They exploit race conditions inside CPU.SEED Labs – Spectre Attack Lab 5 // Flush the values of the array from cache for (i = 0; i < 256; i++) _mm_clflush(&array[i * 4096 +DELTA]);} void victim() {temp = array[secret * 4096 + DELTA];} void reloadSideChannel() {int junk=0; register uint64_t time1, time2; volatile uint8_t * addr; int i; for(i = 0; i < 256; i++){addr = &array[i * 4096 + DELTA]; time1 = __rdtscp(&junk); junk = * addr; time2 = __rdtscp(&junk) - time1; if (time2 <= CACHE_HIT_THRESHOLD){printf("array[%d * 4096 + %d] is ...

From the results we see that the access of array [3*4096] and array [7*4096] is faster than the other arrays on the list. Running the program multiple times gives us similar end results. This is because the two arrays are cached in the CPU cache memory and hence faster access.
