This upload fixes CVE-2023-30577, a backup-user-to-root vulnerability. After fixing this CVE already for unstable (NMU pending, ETA Friday), buster and stretch, I'd also like to fix it for bookworm and bullseye. The patch is taken from upstream [1] and has been merged already there. Package test suite is still happy. [1] https://github.com/zmanda/amanda/pull/228 [ Checklist ] [X] *all* changes are documented in the d/changelog [X] I reviewed all changes and I approve them [X] attach debdiff against the package in (old)stable [ ] the issue is verified as fixed in unstable (as said, pending NMU) I've uploaded the package already to the s-p-u queue. -- Cheers, tobi
