PAM (Pluggable Authentication Modules) is an architecture allowing
|
|
the separation of the development of privilege granting software from
|
|
the development of secure and appropriate authentication schemes.
|
|
SELinux is an operating system based on Linux which includes Mandatory
|
|
Access Control.

|
|
The SELinux patches for PAM introduce a vulnerability allowing a
|
|
password to be checked with the unix_chkpwd utility without delay or
|
|
logging. This vulnerability doesn't affect users who do not run
|
|
SELinux.

</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-libs/pam-0.78-r3"</code>
