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) Resource exhaustion (CVE-ID: CVE-2023-39326)
CWE-ID: CWE-400 - Resource exhaustion
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 application does not properly control consumption of internal resources when handling HTTP chunked requests. A remote attacker can send specially crafted HTTP requests to the server and consume excessive memory resources.
3) Observable discrepancy (CVE-ID: CVE-2023-45287)
CWE-ID: CWE-203 - Observable discrepancy
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/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 access to sensitive information.
The vulnerability exists due to a timing discrepancy when handling RSA based TLS key exchanges. A remote attacker can perform a Marvin attack and gain access to sensitive information.
