Debian LTS: Security Advisory for golang-1.8 (DLA-2592-1)

Published: 2021-03-14 04:00:16
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'golang-1.8' Linux Distribution Package(s) announced via the DLA-2592-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
Several vulnerabilities were discovered in the Go programming language. An attacker could trigger a denial-of-service (DoS), bypasss access control, and execute arbitrary code on the developer's computer. CVE-2017-15041 Go allows 'go get' remote command execution. Using custom domains, it is possible to arrange things so that example.com/pkg1 points to a Subversion repository but example.com/pkg1/pkg2 points to a Git repository. If the Subversion repository includes a Git checkout in its pkg2 directory and some other work is done to ensure the proper ordering of operations, 'go get' can be tricked into reusing this Git checkout for the fetch of code from pkg2. If the Subversion repository's Git checkout has malicious commands in .git/hooks/, they will execute on the system running 'go get.' CVE-2018-16873 The 'go get' command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go Linux Distribution Package, as it may treat the parent directory as a Git repository root, containing malicious configuration. CVE-2018-16874 The 'go get' command is vulnerable to directory traversal when executed with the import path of a malicious Go Linux Distribution Package which contains curly braces (both '{' and '}' characters). The attacker can cause an arbitrary filesystem write, which can lead to code execution. CVE-2019-9741 In net/http, CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the second argument to http.NewRequest with \r\n followed by an HTTP header or a Redis command. CVE-2019-16276 Go allows HTTP Request Smuggling. CVE-2019-17596 Go can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates. CVE-2021-3114 crypto/elliptic/p224.go can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.

Affected Versions:
'golang-1.8' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 9 stretch, these problems have been fixed in version 1.8.1-1+deb9u3. We recommend that you upgrade your golang-1.8 Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
