Description
This security bulletin contains information about 9 vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2021-4024)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the "podman machine" function. A remote attacker can gain unauthorized access to sensitive information on the system.
2) Incorrect authorization (CVE-ID: CVE-2022-2989)
CWE-ID: CWE-863 - Incorrect Authorization
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect handling of the supplementary groups in the Podman container engine. A local user with direct access to the affected container where supplementary groups are used can set access permissions and execute a binary code in that container.
3) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2023-0778)
CWE-ID: CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote attacker to gain compromise the affected system.
The vulnerability exists due to a race condition. A remote attacker can replace a normal file in a volume with a symlink while exporting the volume, allowing for access to arbitrary files on the host file system.
4) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
CWE-ID: CWE-326 - Inadequate Encryption Strength
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
5) Improper Privilege Management (CVE-ID: CVE-2024-1753)
CWE-ID: CWE-269 - Improper Privilege Management
CVSSv4: 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
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.
6) 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.
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.
8) Incorrect authorization (CVE-ID: CVE-2024-23653)
CWE-ID: CWE-863 - Incorrect Authorization
CVSSv4: 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
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.
9) Infinite loop (CVE-ID: CVE-2024-24786)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: 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
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing data in an invalid JSON format within the protojson.Unmarshal() function. A remote attacker can consume all available system resources and cause denial of service conditions.
