Amazon Linux AMI update for golang

1) Input validation error

EUVDB-ID: #VU81964

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-39323

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when processing line directives (e.g. "//line") in the code. A remote attacker can bypass restrictions on "//go:cgo_" directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running "go build".

Mitigation

Update the affected packages:

i686:
    golang-shared-1.20.10-1.48.amzn1.i686
    golang-bin-1.20.10-1.48.amzn1.i686
    golang-1.20.10-1.48.amzn1.i686

noarch:
    golang-misc-1.20.10-1.48.amzn1.noarch
    golang-docs-1.20.10-1.48.amzn1.noarch
    golang-src-1.20.10-1.48.amzn1.noarch

2) Resource exhaustion

EUVDB-ID: #VU82064

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-39325

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Update the affected packages:

i686:
    golang-shared-1.20.10-1.48.amzn1.i686
    golang-bin-1.20.10-1.48.amzn1.i686
    golang-1.20.10-1.48.amzn1.i686

noarch:
    golang-misc-1.20.10-1.48.amzn1.noarch

3) Resource exhaustion

EUVDB-ID: #VU81728

Risk: High

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:H/RL:O/RC:C]

CVE-ID: CVE-2023-44487

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.

Mitigation

Update the affected packages:

i686:
    golang-shared-1.20.10-1.48.amzn1.i686
    golang-bin-1.20.10-1.48.amzn1.i686
