Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU63085

Risk: Medium

CVSSv4.0: 5.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2022-22971

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

2) Input validation error

EUVDB-ID: #VU60007

Risk: Medium

CVSSv4.0: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Green]

CVE-ID: CVE-2021-4034

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

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

The vulnerability exists due to improper handling of the calling parameters count in the pkexec setuid binary, which causes the binary to execute environment variables as commands. A local user can craft environment variables in a way that they will be processed and executed by pkexec and execute arbitrary commands on the system as root.

Mitigation

Install update from vendor's website.
