Mandriva Linux Security Advisory : pam (MDVSA-2010:220)
medium Nessus Plugin ID 50472
Language:
Synopsis
The remote Mandriva Linux host is missing one or more security updates.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:
