|
|
Martin Schulze reported a flaw in the passwd_check() function in
|
|
"libmisc/pwdcheck.c" which is used by chfn and chsh.

<impact type="low">
|
|
<p>
|
|
A logged-in local user with an expired password may be able to use chfn and
|
|
chsh to change his standard shell or GECOS information (full name, phone
|
|
number...) without being required to change his password.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All shadow users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/shadow-4.0.5-r1"</code>
|
