Pull request overview
This PR addresses Go vulnerabilities in the Cloud Shell base Docker image by updating two components: istioctl (from dynamic latest version to pinned v1.28.1) and rootlesskit (from dynamic latest to pinned v2.3.5). These updates resolve several CVEs including CVE-2019-14993, CVE-2021-39155, CVE-2021-39156, and CVE-2022-23635, along with stdlib vulnerabilities requiring Go 1.24.6+.
Key Changes:
- Pinned istioctl to version 1.28.1 with direct GitHub release download
- Pinned rootlesskit to version 2.3.5 (replacing dynamic version lookup)
- Updated installation method for istioctl from legacy script to direct tarball download
