+ <description>
+ <p>
+ Martin Schulze reported a flaw in the passwd_check() function in
+ "libmisc/pwdcheck.c" which is used by chfn and chsh.
+ </p>
+ </description>
+ <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>
+ </resolution>
