Package: release.debian.org Severity: normal Tags: bullseye User: release.debian.org@packages.debian.org Usertags: pu [ Reason ] Bug #940577 reports a command injection vulnerability into deluser which can be exploited by an external entity that can can create strangely named user accounts. This is a privilege escalation on systems that have their account database externally managed, for example in LDAP. This issue is present in adduser since nearly forever (2006) and has just recently been fixed in unstable. [ Impact ] Possible privilege escalation. [ Tests ] Adduser in unstable has an autopkgtest covering the issue; adduser in stable sadly not. [ Risks ] Due to changes in the syntax of the crontab executable, the entire code is non-functional; the only function it provides is thus to offer the command injection. [ Checklist ] [ ] *all* changes are documented in the d/changelog [ ] I reviewed all changes and I approve them [ ] attach debdiff against the package in (old)stable [ ] the issue is verified as fixed in unstable [ Changes ] The suggested fix differs from the fix employed for unstable and just removes the affected code: diff --git a/deluser b/deluser index b1bf56b..c27ec8d 100644 --- a/deluser +++ b/deluser @@ -348,13 +348,6 @@ if($action eq "deluser") { } } - if (system("crontab -l $user >/dev/null 2>&1") == 0) { - # crontab -l returns 1 if there is no crontab - my $crontab = &which('crontab'); - &systemcall($crontab, "-r", $user); - s_print (gtx("Removing crontab ...\n")); - } - s_printf (gtx("Removing user `%s' ...\n"),$user); my @members = get_group_members($maingroup); if (@members == 0) { [ Other info ] This is my first try to do a stable upload. Since adduser is a vital package, but my time is rather limited at the moment, I would like to know whether this fix is acceptable for stable before I prepare an actual package. Also, the fix suggested for stable is not the same fix that is in place in unstable and testing (that one also fixes the broken functionality and adds more safety). Greetings Marc
