Ubuntu 22.04 LTS : Go Networking vulnerabilities (USN-8900-1)

high Nessus Plugin ID 364279

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8900-1 advisory.

 It was discovered that Go Networking did not properly handle server errors after sending a GOAWAY frame during HTTP/2 connection shutdown, which could cause the connection to hang. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2022-27664)

 It was discovered that Go Networking had quadratic complexity when decoding HPACK headers in HTTP/2 streams. A remote attacker could possibly use this issue to cause Go Networking to use excessive resources, leading to a denial of service. (CVE-2022-41723)

 It was discovered that Go Networking incorrectly rendered text nodes outside of the HTML namespace literally, causing text that should be escaped to not be escaped. A remote attacker could possibly use this issue to perform cross-site scripting attacks. (CVE-2023-3978)

 Guido Vranken discovered that Go Networking processed certain inputs to the HTML parsing functions non- linearly with respect to their length. A remote attacker could possibly use this issue to cause Go Networking to use excessive resources, leading to a denial of service. (CVE-2024-45338)

 Sean Ng discovered that Go Networking incorrectly interpreted tags in foreign content with unquoted attribute values ending with a solidus character as self-closing, which could result in content being placed in the wrong scope during DOM construction. A remote attacker could possibly use this issue to perform cross-site scripting attacks. (CVE-2025-22872)

 It was discovered that Go Networking had quadratic parsing complexity when processing certain HTML inputs.
 A remote attacker could possibly use this issue to cause Go Networking to use excessive resources, leading to a denial of service. (CVE-2025-47911)

 It was discovered that Go Networking could enter an infinite loop when parsing certain HTML inputs. A remote attacker could possibly use this issue to cause Go Networking to use excessive resources, leading to a denial of service. (CVE-2025-58190)

 It was discovered that Go Networking incorrectly accepted Punycode-encoded labels that decoded to ASCII- only labels when processing internationalized domain names. A remote attacker could possibly use this issue to bypass access control restrictions and escalate privileges. (CVE-2026-39821)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected golang-golang-x-net-dev package.
