Fedora 41 update for podman-tui

1) Path traversal

EUVDB-ID: #VU98828

Risk: Low

CVSSv3.1: 4.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-9675

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

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

The vulnerability exists due to input validation error when processing directory traversal sequences in cache mounts. A local user can execute a 'RUN' instruction in a Container file to mount an arbitrary directory from the host into the container as long as those files can be accessed by the user running Buildah.

Mitigation

Install updates from vendor's repository.

2) Security features bypass

EUVDB-ID: #VU85991

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]

CVE-ID: CVE-2024-21626

CWE-ID: CWE-254 - Security Features

Exploit availability: Yes

Description

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

The vulnerability exists due to an internal file descriptor leak that can cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace or a malicious image to allow a container process to gain access to the host filesystem through runc run. A remote attacker can trick the victim into loading a malicious image to bypass sandbox restrictions and execute arbitrary code on the host OS.

Mitigation

Install updates from vendor's repository.

3) UNIX symbolic link following

EUVDB-ID: #VU98817

Risk: Low

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-9676

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a symlink following issue when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). A local user can create a symbolic link to an arbitrary file on the system, force the library to read it and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
