Category:FreeBSD Local Security Checks
Title:FreeBSD Security Advisory (FreeBSD-SA-06:12.opie.asc)
Summary:The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-06:12.opie.asc
Description:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-06:12.opie.asc

Vulnerability Insight:
OPIE is a one-time password system designed to help to secure a system
against replay attacks. It does so using a secure hash function and a
challenge/response system. The opiepasswd(1) program is used to set
up OPIE authentication for a user. OPIE is enabled by default on
FreeBSD through PAM.

The opiepasswd(1) program uses getlogin(2) to identify the user
calling opiepasswd(1). In some circumstances getlogin(2) will return
root even when running as an unprivileged user. This causes
opiepasswd(1) to allow an unpriviled user to configure OPIE
authentication for the root user.

Solution:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date.
