Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-4235)
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 parsing YAML files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2022-2880)
The vulnerability allows a remote attacker to perform parameter smuggling attacks.
The vulnerability exists due to incorrect handling of requests forwarded by ReverseProxy in net/http/httputil. A remote attacker can supply specially crafted parameters that cannot be parsed and are rejected by net/http and force the application to include these parameters into the forwarding request. As a result, a remote attacker can smuggle potentially dangerous HTTP parameters into the request.
3) Improper access control (CVE-ID: CVE-2022-2995)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to incorrect handling of the supplementary groups. A local user can bypass implemented security restrictions, leading to sensitive information disclosure or possible data modification.
4) Improper access control (CVE-ID: CVE-2022-3162)
The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. Users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different kind in the same API group they are not authorized to read.
5) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2022-3172)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in kube-apiserver. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
6) Protection Mechanism Failure (CVE-ID: CVE-2022-3259)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to missing HTTP Strict Transport Security (HSTS) header. A remote attacker can perform MitM attack.
7) Configuration (CVE-ID: CVE-2022-3466)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a missing fix for #VU62796 (CVE-2022-27652) in previous release of the cri-o red hat package. A local user can escalate privileges on the system.
8) Input validation error (CVE-ID: CVE-2022-27664)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
9) Resource exhaustion (CVE-ID: CVE-2022-30631)
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 in Reader.Read method when handling an archive that contains a large number of concatenated 0-length compressed files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
10) Security features bypass (CVE-ID: CVE-2022-32148)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to unexpected behavior of httputil.ReverseProxy.ServeHTTP. When the method is called with a Request.Header map containing a nil value for the X-Forwarded-For header, ReverseProxy would set the client IP as the value of the X-Forwarded-For header, contrary to its documentation.
11) Input validation error (CVE-ID: CVE-2022-32189)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in
Float.GobDecode. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
12) Resource exhaustion (CVE-ID: CVE-2022-41715)
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 in regexp/syntax when handling regular expressions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
13) Incorrect default permissions (CVE-ID: CVE-2022-27652)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to containers are incorrectly started with non-empty default permissions within in Moby (Docker Engine). An attacker with access to programs with inheritable file capabilities can elevate those capabilities to the permitted set when execve(2) runs.
