Synopsis:          Moderate: pam security update

Issue date:        2010-11-01

CVE Names:         CVE-2010-3316

 		   CVE-2010-3435

 		   CVE-2010-3853



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)



It was discovered that 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)
