Security updates for Debian 12
Fixes are backported by the Debian Security Team, and later the Debian LTS team, announced as DSA or DLA advisories and recorded in the Debian Security Tracker. Read more about how security updates work on Debian.
How OS Checker tracks it
OS Checker compares each machine's installed packages against Debian's main archive and security archive. For every outdated package, the Debian Security Tracker tells whether the available version fixes a known CVE, which makes it vulnerable rather than just outdated. Fixes published only through Freexian's ELTS repository aren't tracked.
