Description

This security bulletin contains information about 3 vulnerabilities.


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

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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) Observable discrepancy (CVE-ID: CVE-2023-45287)

CWE-ID: CWE-203 - Observable discrepancy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a timing discrepancy when handling RSA based TLS key exchanges. A remote attacker can perform a Marvin attack and gain access to sensitive information.


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

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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).
