Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Improper Validation of Array Index (CVE-ID: CVE-2020-28852)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of array index in language.ParseAcceptLanguage while processing a BCP 47 tag. A remote attacker can send a specially crafted HTTP request containing a malformed HTTP Accept-Language header and perform a denial of service (DoS) attack.
2) Information disclosure (CVE-ID: CVE-2021-4024)
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.
3) Origin validation error (CVE-ID: CVE-2021-20199)
The vulnerability allows a remote attacker to bypass security restrictions.
The vulnerability exists due to missing authentication when connecting from all sources. A remote attacker can send a specially crafted request and bypass access restrictions to containerized applications.
4) Improper locking (CVE-ID: CVE-2021-20291)
The vulnerability allows a local user to perform a denial of service attack (DoS) on the target system.
The vulnerability exists due to double-locking error. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).
5) Missing Authorization (CVE-ID: CVE-2021-33197)
The vulnerability allows a remote attacker to bypass authorization process.
The vulnerability exists due to an error in some configurations of ReverseProxy (from net/http/httputil). A remote attacker can drop arbitrary headers and bypass authorization process.
6) Improper Certificate Validation (CVE-ID: CVE-2021-34558)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper certificate verification in crypto/tls package in Go when processing X.509 certificates. The application does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.
7) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-27191)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.
