# Security digest: March 29, 2024

1 editorial brief.

## Take stock

- Check exposure: xz backdoor . Anyone who ran Debian testing/unstable, Fedora 41/Rawhide or another rolling distribution with xz 5.6.0 or 5.6.1 in early 2024, or who still has those tarballs in a build pipeline or container image.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Check exposure** [xz-utils Backdoor in liblzma 5.6.0/5.6.1 (CVE-2024-3094)](https://erroneo.us/security/briefs/xz-utils-backdoor/index.md): The backdoor only reached rolling and pre-release distributions for a few weeks before discovery; stable enterprise releases never shipped it, but any machine that ran xz 5.6.0 or 5.6.1 should be checked.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
