Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU9883
Risk: Low
CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2017-5715
CWE-ID:
CWE-200 - Exposure of sensitive information to an unauthorized actor
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in Intel CPU hardware due to improper implementation of the speculative execution of instructions. A local attacker can utilize branch target injection, execute arbitrary code, perform a side-channel attack and read sensitive memory information.
MitigationUpdate the affected package intel-microcode to the latest version.
Vulnerable software versionsUbuntu: 14.04 - 21.04
intel-microcode (Ubuntu package): before 3.20210608.0u buntu0.20.04.1
CPE2.3https://ubuntu.com/security/notices/USN-4985-1
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
EUVDB-ID: #VU54191
Risk: Low
