SB2024080729 - Gentoo update for Go

Description

This security bulletin contains information about 13 secuirty vulnerabilities.

1) Cross-site scripting (CVE-ID: CVE-2023-24539)

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 when handling angle brackets in CSS context. A remote attacker can inject 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.

2) Code Injection (CVE-ID: CVE-2023-24540)

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation when processing whitespace characters. A remote attacker can send a specially crafted request and execute arbitrary JavaScript code.

3) Cross-site scripting (CVE-ID: CVE-2023-29400)

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 when processing HTML attributes. A remote attacker can trick the victim to follow a specially crafted link 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.

4) Resource exhaustion (CVE-ID: CVE-2023-39326)

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.

5) Input validation error (CVE-ID: CVE-2023-45283)

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to the path/filepath package does not recognize paths with a "??" prefix as Root Local Device path prefix. A local user can abuse such behavior and bypass implemented security restrictions.

6) Missing Encryption of Sensitive Data (CVE-ID: CVE-2023-45285)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to a fallback to insecure git. Using "go get" to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and  git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. OPROXY=off).

7) Resource exhaustion (CVE-ID: CVE-2023-45288)

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

The vulnerability exists due to insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single HTTP/2 stream. A remote attacker can send specially crafted HTTP/2 requests to the server and perform a denial of service (DoS) attack.

8) 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.

9) 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.

10) 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.

11) 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.

12) 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.

13) Infinite loop (CVE-ID: CVE-2024-24788)

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

The vulnerability exists due to infinite loop when processing DNS responses. A remote attacker can send a specially crafted DNS response to the application and cause denial of service conditions.
