Gentoo: GLSA-200710-15: KDM: Local privilege escalation
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200710-15 https://security.gentoo.org/
Severity: High Title: KDM: Local privilege escalation Date: October 14, 2007 Bugs: #192373 ID: 200710-15
Synopsis ======= KDM allows logins without password under certain circumstances allowing a local user to gain elevated privileges.
Background ========= KDM is the Display Manager for the graphical desktop environment KDE. It is part of the kdebase package.
Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-base/kdm < 3.5.7-r2 >= 3.5.7-r2 2 kde-base/kdebase < 3.5.7-r4 >= 3.5.7-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
========== Kees Huijgen discovered an error when checking the credentials which can lead to a login without specifying a password. This only occurswhen auto login is configured for at least one user and a password is required to shut down the machine.
Impact ===== A local attacker could gain root privileges and execute arbitrary commands by logging in as root without specifying root's password.
Workaround ========= There is no known workaround at this time.
Resolution ========= All KDM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdm-3.5.7-r2"
All kdebase users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdebase-3.5.7-r4"
