"The remote NewStart CGSL host, running version MAIN 6.06 (SP), has pam packages installed that are affected by multiple
vulnerabilities:

  - pam_namespace.c in the pam_namespace module in Linux-PAM (aka pam) before 1.1.3 uses the environment of
    the invoking application or service during execution of the namespace.init script, which might allow local
    users to gain privileges by running a setuid program that relies on the pam_namespace PAM check, as
    demonstrated by the sudo program. (CVE-2010-3853)

  - pam_unix.so in Linux-PAM 0.99.7.0 allows context-dependent attackers to log into accounts whose password
    hash, as stored in /etc/passwd or /etc/shadow, has only two characters. (CVE-2007-0003)

  - Linux-PAM before 1.0.4 does not enforce the minimum password age (MINDAYS) as specified in /etc/shadow,
    which allows local users to bypass intended security policy and change their passwords sooner than
    specified. (CVE-2009-0579)

  - The run_coprocess function in pam_xauth.c in the pam_xauth module in Linux-PAM (aka pam) before 1.1.2 does
    not check the return values of the setuid, setgid, and setgroups system calls, which might allow local
    users to read arbitrary files by executing a program that relies on the pam_xauth PAM check.
    (CVE-2010-3316)

  - The (1) pam_env and (2) pam_mail modules in Linux-PAM (aka pam) before 1.1.2 use root privileges during
    read access to files and directories that belong to arbitrary user accounts, which might allow local users
    to obtain sensitive information by leveraging this filesystem activity, as demonstrated by a symlink
    attack on the .pam_environment file in a user's home directory. (CVE-2010-3435)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
