Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Unprotected Alternate Channel (CVE-ID: CVE-2023-28840)
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)
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)
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)
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)
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)
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)
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.
