Description
This security bulletin contains information about 3 vulnerabilities.
1) Security features bypass (CVE-ID: CVE-2024-21626)
CWE-ID: CWE-254 - Security Features
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an internal file descriptor leak that can cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace or a malicious image to allow a container process to gain access to the host filesystem through runc run. A remote attacker can trick the victim into loading a malicious image to bypass sandbox restrictions and execute arbitrary code on the host OS.
2) Improper access control (CVE-ID: CVE-2023-27561)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/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 compromise the target system.
The vulnerability exists due to improper access restrictions in the libcontainer/rootfs_linux.go. A local user can gain elevated privileges on the target system.
3) Improper Preservation of Permissions (CVE-ID: CVE-2023-28642)
CWE-ID: CWE-281 - Improper preservation of permissions
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/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 improper preservation of permissions in the AppArmor and SELinux when /proc inside the container is symlinked with a specific mount configuration. A remote attacker can gain access to the target application.
