Architecture: source
Version: 2:2.4-2+deb12u3
Distribution: bookworm-security
Urgency: high
Maintainer: Guillem Jover <guillem@debian.org>
Changed-By: Guillem Jover <guillem@debian.org>
Closes: 1130741 1130742
Changes:
inetutils (2:2.4-2+deb12u3) bookworm-security; urgency=high
.
* Add patch from upstream:
- Prevent privilege escalation via telnetd abusing systemd service
credentials support added to the login(1) implementation of util-linux in
release 2.40. Reported by Ron Ben Yizhak <ron.benyizhak@safebreach.com>.
Fixes CVE-2026-28372.
- Ignore all environment options from clients unless the variable was
listed in the new --accept-env telnetd option. This mitigates privilege
escalation using environment variables.
This is the complete fix for CVE-2026-24061, with its own CVE pending.
- Fix stack buffer overflow processing SLC suboption triplets.
Reported by Adiel Sol, Arad Inbar, Erez Cohen, Nir Somech, Ben Grinberg,
Daniel Lubel at DREAM Security Research Team.
Fixes CVE-2026-32746. (Closes: #1130742)
* Add the hashcode-string1 module from forky/sid gnulib adapted to bookworm
required by the --accept-env patch, and the gl_hash_set, gl_set, gl_xset
and gl_anyhash bookworm gnulib modules required by hashcode-string1.
Inject new gnulib modules in lib/Makefile.am.
* Adapt netkit-telnet patch to not leak unexported environment variables to
telnetd. Reported by Justin Swartz <justin.swartz@risingedge.co.za>.
Fixes CVE-2026-32772. (Closes: #1130741)
* Prevent user local privilege escalation using --debug, which was
susceptible to symlink attacks, or leaking on-wire credentials to a
user that had pre-created the file and kept it open. Fix by switching
from /tmp/telnet.debug to /run/telnet/debug.<pid>, and making the
setup error checks fatal.
Partially reported by Justin Swartz <justin.swartz@risingedge.co.za>.
* Update local telnetd man page to match new --debug behavior.
