Description
This security bulletin contains information about 5 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2020-10722)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in check log functionality. A remote attacker can pass specially crafted input to the application, trigger mmap offset and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2020-10723)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of translated addresses. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Cryptographic issues (CVE-ID: CVE-2020-10724)
CWE-ID: CWE-310 - Cryptographic Issues
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to incorrect validation of keys lengths. A remote attacker can bypass certain security restrictions.

CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak. A remote attacker can force the application to leak memory and perform denial of service attack.
5) Memory leak (CVE-ID: CVE-2020-10726)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak, related to fd leak and vring index check. A remote attacker can force the application to leak memory and read sensitive information or perform denial of service attack.
