Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU98141

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-9341

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied input. When FIPS mode is enabled on a system, container runtimes may incorrectly handle certain file paths due to improper validation in the containers/common Go library. This flaw allows an attacker to exploit symbolic links and trick the system into mounting sensitive host directories inside a container.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 41

podman: before 5.2.5-1.fc41

containers-common: before 0.60.4-4.fc41

buildah: before 1.37.5-1.fc41

https://bodhi.fedoraproject.org/updates/FEDORA-2024-5a61a2fa45


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated privileged user via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Path traversal

EUVDB-ID: #VU98828

Risk: Low

CVSSv4.0: 1.1 [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]

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.

Vulnerable software versions

Fedora: 41

podman: before 5.2.5-1.fc41

containers-common: before 0.60.4-4.fc41

buildah: before 1.37.5-1.fc41

CPE2.3 External links

https://bodhi.fedoraproject.org/updates/FEDORA-2024-5a61a2fa45


Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) UNIX symbolic link following

EUVDB-ID: #VU98817

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

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.
