Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2024-24786)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop when parsing data in an invalid JSON format within the protojson.Unmarshal() function. A remote attacker can consume all available system resources and cause denial of service conditions.


2) Resource exhaustion (CVE-ID: CVE-2023-52425)

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 large tokens. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) XML Entity Expansion (CVE-ID: CVE-2023-52426)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to recursive XML Entity Expansion if XML_DTD is undefined at compile time. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


4) Error Handling (CVE-ID: CVE-2024-24783)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in crypto/x509 due to improper validation of a certificate chain that contains an unknown public key. A remote attacker can pass a specially crafted certificate to the application and perform a denial of service attack.


5) Resource exhaustion (CVE-ID: CVE-2023-45290)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in net/http due to application does not properly control consumption of internal resources when parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile). A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


6) Information disclosure (CVE-ID: CVE-2023-45289)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to insecure forwarding of headers and cookies to a third-party domains in net/http and net/http/cookiejar. A remote attacker can trick the application into sharing sensitive information with an attacker-controlled website.


7) Cross-site scripting (CVE-ID: CVE-2024-24785)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in html/template when parsing errors returned from MarshalJSON methods. A remote attacker can execute arbitrary HTML and script code in user's browser in context of vulnerable website.


8) Input validation error (CVE-ID: CVE-2024-24784)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of display names within the ParseAddressList function in net/mail. A remote attacker can pass specially crafted input to the application and perform a spoofing attack.
