Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Code Injection (CVE-ID: CVE-2023-24538)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation in html/template when handling JavaScript templates that contain backticks in code. If a template contains a Go template action within a JavaScript template literal, the contents of the action can be used to terminate the literal, injecting arbitrary JavaScript code into the Go template.


2) Infinite loop (CVE-ID: CVE-2023-24537)

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

The vulnerability exists due to infinite loop when calling any of the Parse functions on Go source code which contains //line directives with very large line numbers. A remote attacker can consume all available system resources and cause denial of service conditions.


3) Resource management error (CVE-ID: CVE-2023-24536)

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 mime/multipart and net/textproto components when parsing multipart forms. A remote attacker can pass specially crafted request to the application and perform a denial of service (DoS) attack.


4) Resource exhaustion (CVE-ID: CVE-2023-24534)

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 HTTP and MIME headers in net/textproto. A remote attacker can cause an HTTP server to allocate large amounts of memory from a small request and perform a denial of service (DoS) attack.
