SB2023121157 - SUSE update for go1.20

Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) 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.

2) Input validation error (CVE-ID: CVE-2023-45284)

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

The vulnerability exists due to the IsLocal() function from the path/filepath package does not correctly detect reserved device names in some cases when executed on Windows. Reserved names followed by spaces, such as "COM1 ", and reserved names "COM" and "LPT" followed by superscript 1, 2, or 3, are incorrectly reported as local. A local user can abuse such behavior and bypass implemented security restrictions.

3) 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).

Remediation
