Description

This security bulletin contains information about 6 vulnerabilities.

1) Out-of-bounds read (CVE-ID: CVE-2021-22918)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/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 gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in uv__idna_toascii() function in libuv, which is used to convert strings to ASCII. A remote attacker can force the application to resolve a specially crafted hostname, trigger an out-of-bounds read error and gain access to sensitive information or perform a denial of service (DoS) attack.

2) Incorrect default permissions (CVE-ID: CVE-2021-22921)

CWE-ID: CWE-276 - Incorrect Default Permissions

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in Windows installer due to incorrect default permissions for files and folders that are set by the application. A local user with access to the system can view contents of files and directories or modify them.

3) Improper Certificate Validation (CVE-ID: CVE-2021-22939)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to incomplete validation of rejectUnauthorized parameter. A remote attacker can cause the connections to servers with an expired certificate would have been accepted.

4) Improper input validation (CVE-ID: CVE-2021-22931)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Cluster: General (Node.js) component in MySQL Cluster. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.

5) Use-after-free (CVE-ID: CVE-2021-22940)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error. A remote attacker can change process behavior.

6) Use-after-free (CVE-ID: CVE-2021-22930)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing HTTP/2 stream canceling requests. A remote attacker can send a specially crafted HTTP/2 request, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
