RHSA-2010:0819-01: [RHSA-2010:0819-01] pam: Multiple Vulnerabilities
Product: Red Hat Enterprise Linux
Description:
It was discovered that 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)
It was discovered that 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)
