Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2021-39293)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of archive/zip in Go programming language when processing archive header. A remote attacker can pass a specially crafted file to the application and perform a denial of service (DoS) attack.
2) Unchecked Return Value (CVE-ID: CVE-2022-23806)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to unchecked return value within the Curve.IsOnCurve() function in crypto/elliptic. A remote attacker can force the application to incorrectly return true in situations with a big.Int value that is not a valid field element. As a result, an attacker can modify application flow, which can lead to unauthorized data modification or denial of service.
3) Input validation error (CVE-ID: CVE-2021-43565)
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 when parsing a Signer to ServerConfig.AddHostKey in cases where the Signer passed to AddHostKey does not implement AlgorithmSigner or the Signer passed to AddHostKey returns a key of type “ssh-rsa” from its PublicKey method. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Resource exhaustion (CVE-ID: CVE-2021-44717)
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 processing HTTP/2 requests. A remote attacker can send multiple HTTP/2 requests to the server and exhaust all available memory resources.
5) Incorrect authorization (CVE-ID: CVE-2022-23773)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists within cmd/go, which can misinterpret branch names that falsely appear to be version tags. This can lead to a situation where an attacker can bypass implemented security restrictions and perform restricted actions, e.g. create tags when access was granted to create branches only.
6) Input validation error (CVE-ID: CVE-2021-44716)
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. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
7) Resource exhaustion (CVE-ID: CVE-2022-23772)
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 within the Rat.SetString(0 function in math/big. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
8) Race condition (CVE-ID: CVE-2021-36221)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in net/http/httputil ReverseProxy when handling ErrAbortHandler events. A remote attacker can trigger a race condition and crash the ReverseProxy.
9) Input validation error (CVE-ID: CVE-2021-29923)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of user-supplied input in net.ParseIP and net.ParseCIDR, as the Go interpreter does not properly consider extraneous zero characters at the beginning
of an IP address octet. A remote attacker can
bypass access control that is based on IP addresses, because of
unexpected octal interpretation.
10) 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.
11) Resource management error (CVE-ID: CVE-2021-33198)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when handling a large exponent to the math/big.Rat SetString or UnmarshalText method. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
12) 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.
13) Resource exhaustion (CVE-ID: CVE-2021-33196)
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 archives. A remote attacker can pass a specially crafted .zip file to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
14) Cross-site scripting (CVE-ID: CVE-2021-33195)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of data passed from DNS lookups. A remote attacker can send a specially crafted DNS reqponse and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
15) Infinite loop (CVE-ID: CVE-2021-33194)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop. A remote attacker can pass crafted ParseFragment input to the application, consume all available system resources and cause denial of service conditions.
16) Uncontrolled Recursion (CVE-ID: CVE-2021-31525)
The vulnerability allows a remote attacker to perform a DoS attack.
The vulnerability exists due to uncontrolled recursion when processing HTTP headers. A remote attacker can send a large header to ReadRequest or ReadResponse and perform a denial of service (DoS) attack.
