Description

This security bulletin contains information about 5 vulnerabilities.


1) Security restrictions bypass (CVE-ID: CVE-2022-1227)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 8.4 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to improper privilege management when running podman top on a container made from a maliciously-crafted image and using a user namespace. An attacker with full access to the container can execute arbitrary code  in the host context.


2) Input validation error (CVE-ID: CVE-2022-21698)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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 within method label cardinality. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-27649)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to excess inheritable capabilities set, which leads to security restrictions bypass and privilege escalation.


4) Improper privilege management (CVE-ID: CVE-2022-27650)

CWE-ID: CWE-269 - Improper Privilege Management

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to elevate privileges.

The vulnerability exists due to improper privilege management in crun exec when creating processes inside a linux container. A local user can execute a program with inheritable file capabilities to elevate privileges.

The issue creates a non-empty inheritable capability set by default, but the inheritable set does not exceed the container's bounding set.


5) Incorrect default permissions (CVE-ID: CVE-2022-27651)

CWE-ID: CWE-276 - Incorrect Default Permissions

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to incorrect default permissions for files and folders that are set by the application. A remote attacker can view contents of files and directories or modify them.
