GLSA-200501-22 : poppassd_pam: Unauthorized password changing

critical Nessus Plugin ID 16413

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-22 (poppassd_pam: Unauthorized password changing)

 Gentoo Linux developer Marcus Hanwell discovered that poppassd_pam did not check that the old password was valid before changing passwords. Our investigation revealed that poppassd_pam did not call pam_authenticate before calling pam_chauthtok.
 Impact :

 A remote attacker could change the system password of any user, including root. This leads to a complete compromise of the POP accounts, and may also lead to a complete root compromise of the affected server, if it also provides shell access authenticated using system passwords.
 Workaround :

 There is no known workaround at this time.

Solution

All poppassd_pam users should migrate to the new package called poppassd_ceti:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/poppassd_ceti-1.8.4' Note: Portage will automatically replace the poppassd_pam package by the poppassd_ceti package.
