LXD vulnerable to Race Condition

CVE-2015-1340GHSA-8mpq-fmr3-6jxv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/lxc/lxd 0.0.0-20151004155856-19c6961cc101), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

LXD before version 0.19-0ubuntu5 doUidshiftIntoContainer() has an unsafe Chmod() call that races against the stat in the Filepath.Walk() function.

# Patch Next advisory brief: CVE-2015-1340

Advisory: LXD vulnerable to Race Condition
IDs: CVE-2015-1340, GHSA-8mpq-fmr3-6jxv
Record: https://patchnext.com/advisories/cve-2015-1340 (revision 1, source checked 26 Oct 2026, 14:59 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/lxc/lxd 0.0.0-20151004155856-19c6961cc101. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/lxc/lxd: affected < 0.0.0-20151004155856-19c6961cc101; fixed in 0.0.0-20151004155856-19c6961cc101

## Suggested inspection (read-only)
- Go github.com/lxc/lxd: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/lxc/lxd.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-8mpq-fmr3-6jxv (GitHub-reviewed advisory GHSA-8mpq-fmr3-6jxv lists affected ranges: Go github.com/lxc/lxd >=0 <0.0.0-20151004155856-19c6961cc101)
