USN-7197-1: Go Networking vulnerability
9 January 2025

golang-golang-x-net could be made to crash if it received specially crafted network traffic.

Releases

• Ubuntu 24.10
• Ubuntu 24.04 LTS
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages
adsys - AD SYStem integration
golang-golang-x-net - Supplementary Go networking libraries
golang-golang-x-net-dev - Supplementary Go networking libraries
juju-core - next generation service orchestration system

Details
Guido Vranken discovered that Go Networking handled input to the Parse
functions inefficiently. An attacker could possibly use this issue to
cause denial of service. This update addresses the issue in the
golang-golang-x-net and golang-golang-x-net-dev packages, as well as the
library vendored within adsys and juju-core.

Update instructions
The problem can be corrected by updating your system to the following package versions:

Ubuntu 24.10

• adsys - 0.15.2ubuntu0.1
• adsys-windows - 0.15.2ubuntu0.1
  Ubuntu 24.04
• adsys - 0.14.3~24.04ubuntu0.1
• adsys-windows - 0.14.3~24.04ubuntu0.1
• golang-golang-x-net-dev - 1:0.21.0+dfsg-1ubuntu0.1~esm1
• Available with Ubuntu Pro
  Ubuntu 22.04
