Mandriva Linux Security Advisory : pam (MDVSA-2010:220)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.

Synopsis :

The remote Mandriva Linux host is missing one or more security

Description :

Multiple vulnerabilities were discovered and corrected in pam :

The pam_xauth module did not verify the return values of the setuid()
and setgid() system calls. A local, unprivileged user could use this
flaw to execute the xauth command with root privileges and make it
read an arbitrary input file (CVE-2010-3316).

The pam_mail module used root privileges while accessing users' files.
In certain configurations, a local, unprivileged user could use this
flaw to obtain limited information about files or directories that
they do not have access to (CVE-2010-3435).

The pam_namespace module executed the external script namespace.init
with an unchanged environment inherited from an application calling
PAM. In cases where such an environment was untrusted (for example,
when pam_namespace was configured for setuid applications such as su
or sudo), a local, unprivileged user could possibly use this flaw to
escalate their privileges (CVE-2010-3853).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
