SB2025050132 - Ubuntu update for docker.io

Description

This security bulletin contains information about 7 vulnerabilities.

1) Unprotected Alternate Channel (CVE-ID: CVE-2023-28840)

CWE-ID: CWE-420 - Unprotected Alternate Channel

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

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

The vulnerability exists due to unprotected alternate channel within encrypted overlay networks. A remote attacker can inject arbitrary Ethernet frames into the encrypted overlay network and perform a denial of service (DoS) attack.

2) Missing Encryption of Sensitive Data (CVE-ID: CVE-2023-28841)

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

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

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

The vulnerability exists due to missing encryption of sensitive data within the overlay network driver. A remote attacker can gain unauthorized access to sensitive information on the system.

3) Unprotected Alternate Channel (CVE-ID: CVE-2023-28842)

CWE-ID: CWE-420 - Unprotected Alternate Channel

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

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

The vulnerability exists due to unprotected alternate channel within encrypted overlay networks. A remote attacker can inject arbitrary Ethernet frames into the encrypted overlay network by encapsulating them in VXLAN datagrams.

4) Race condition (CVE-ID: CVE-2024-23651)

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

CVSSv4: 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

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.

5) Race condition (CVE-ID: CVE-2024-36621)

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

CVSSv4: 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

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

The vulnerability exists due to a race condition within builder/builder-next/adapters/snapshot/layer.go. A local user can exploit the race and perform a denial of service (DoS) attack.

6) Race condition (CVE-ID: CVE-2024-36623)

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

CVSSv4: 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

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

The vulnerability exists due to a race condition in the streamformatter package. A local user can exploit the race and crash the application.

7) Path traversal (CVE-ID: CVE-2024-23652)

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

CVSSv4: 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

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.
