Description Marcin Garski 2005-02-09 23:04:17 UTC

shadow-4.0.5 has fixed securirty bug in libmisc/pwdcheck.c which allow
unauthorized account properties modification. Affected tools: chfn and
chsh. As I see patch can be easily backported.

Comment 1 Marcin Garski 2005-02-09 23:05:34 UTC

I don't have access to RHEL but probably RHEL could use afected version.

Comment 2 Mark J. Cox 2005-02-11 11:38:12 UTC

Note that the scope of this issue is for a user, who is logged in but
has an expired password to alter his account information with chfn or
chsh without having to change the password.

RHEL uses chfn/chsh from util-linux and not from shadow-utils and is
unaffected by this issue
