MDVSA-2010:220: [MDVSA-2010:220] pam – Fix for Multiple Vulnerabilities
Problem 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).
