Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Improper Privilege Management

EUVDB-ID: #VU87616

Risk: High

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

CVE-ID: CVE-2024-1753

CWE-ID: CWE-269 - Improper Privilege Management

Exploit availability: No

Description

The vulnerability allows a remote attacker to escalate privileges.

The vulnerability exists due to the affected application allows containers to mount arbitrary locations on the host filesystem into build containers. A remote attacker can escalate privileges.

Mitigation

Update the affected packages.
app-containers/buildah to version: 1.35.3

Vulnerable software versions

Gentoo Linux: All versions

app-containers/buildah: before 1.35.3

CPE2.3 External links

https://security.gentoo.org/glsa/202407-25


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

2) Race condition

EUVDB-ID: #VU86035

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-23651

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

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

The vulnerability exists due to a race condition. A remote attacker can exploit the race and cause the files from the host system being accessible to the build container.

Mitigation

Update the affected packages.
app-containers/buildah to version: 1.35.3

Vulnerable software versions

Gentoo Linux: All versions

app-containers/buildah: before 1.35.3

CPE2.3 External links

https://security.gentoo.org/glsa/202407-25


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

3) Path traversal

EUVDB-ID: #VU86037

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-23652

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences within BuildKit frontend or Dockerfile using RUN --mount. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.

Mitigation

Update the affected packages.
app-containers/buildah to version: 1.35.3

Vulnerable software versions

Gentoo Linux: All versions

app-containers/buildah: before 1.35.3

CPE2.3 External links

https://security.gentoo.org/glsa/202407-25


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

4) Incorrect authorization

EUVDB-ID: #VU86038

Risk: High

CVSSv4.0: 8.9 [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:P/U:Amber]

CVE-ID: CVE-2024-23653

CWE-ID: CWE-863 - Incorrect Authorization

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to bypass authorization checks.

The vulnerability exists due to interactive containers API does not validate entitlements check. A remote attacker can use these APIs to ask BuildKit to run a container with elevated privileges.

Mitigation

Update the affected packages.
app-containers/buildah to version: 1.35.3

Vulnerable software versions

Gentoo Linux: All versions

app-containers/buildah: before 1.35.3

CPE2.3 External links

https://security.gentoo.org/glsa/202407-25


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

5) Infinite loop

EUVDB-ID: #VU87326

Risk: Medium

CVSSv4.0: 6.6 [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/E:U/U:Green]

CVE-ID: CVE-2024-24786

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

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