Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU27395
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-11868
CWE-ID:
CWE-290 - Authentication Bypass by Spoofing
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication and perform a denial of service (DoS) attack.
The vulnerability exists due to ntpd allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp.A remote attacker can bypass authentication and block synchronization.
MitigationUpdate the affected packages.

EUVDB-ID: #VU26241
Risk: Low
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-13817
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to ntpd uses highly predictable timestamps that can allow spoofing attack over IPv4 or a denial of service attack. A remote non-authenticated attacker can modify clock on the client NTP server to terminate it.
Update the affected packages.

Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-15025
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak when processing CMAC authentication. A remote attacker can force the application to leak memory and perform denial of service attack.
MitigationUpdate the affected packages.
