Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Information disclosure
EUVDB-ID: #VU13850
Risk: Low
CVSSv3.1: 3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-3693
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in the design of most modern CPUs using speculative execution and branch prediction due to improper speculative execution of instructions. A local attacker can bypass bounds checks, trigger buffer overflow, perform arbitrary speculative execution and a side-channel attack to access sensitive memory information.
