All supported architectures
The login program included in util-linux could leak sensitive information
under certain conditions.
Util-linux is a suite of essential system utilites, including login,
In some situations the login program could leak sensitive data due to an
incorrect usage of a reallocated pointer.
NOTE: Only users who have PAM support disabled on their
systems (i.e. -PAM in their USE variable) will be affected by this
vulnerability. By default, this USE flag is enabled on all
architectures. Users with PAM support on their system receive login binaries
as part of the pam-login package, which remains unaffected.
A remote attacker may obtain sensitive data.
A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.
All util-linux users should upgrade to version 2.12 or later:
Code Listing 3.1: Resolution
# emerge sync
# emerge ">=sys-apps/util-linux-2.12"
