Package        : inetutils
CVE ID         : CVE-2026-24061
Debian Bug     : 1126047

Kyu Neushwaistein discovered that telnetd from inetutils does not
sanitize the USER environment variable before passing it on to login. A
remote attacker can take advantage of this flaw to login as root,
bypassing normal authentication processes.

For the oldstable distribution (bookworm), this problem has been fixed
in version 2:2.4-2+deb12u2.

For the stable distribution (trixie), this problem has been fixed in
version 2:2.6-3+deb13u1.

We recommend that you upgrade your inetutils packages.

For the detailed security status of inetutils please refer to its
security tracker page at:
