  1. Problem description:

I OpenPegasus PAM Authentication Buffer Overflow

Alexander Sotirov from VMware Security Research discovered a
buffer overflow vulnerability in the OpenPegasus Management server.
This flaw could be exploited by a malicious remote user on the
service console network to gain root access to the service console.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2007-5360 to this issue.

RPM Updated: pegasus-2.5-552927
VM Shutdown: No
Host Reboot: No

Note: ESX Server 3.5 and ESX Server 3i are not affected by this
issue.

ESX Server 2.5.x

Users should remove the OpenPegasus CIM Management rpm. This
component is disabled by default, and VMware recommends that you
do not use this component of ESX Server 2.x. If you want to
use the CIM functionality, upgrade to ESX Server 3.0.1 or a later
release.

Note: This vulnerability can be exploited remotely only if the
attacker has access to the service console network.

     Security best practices provided by VMware recommend that the
     service console be isolated from the VM network. Please see
     http://www.vmware.com/resources/techresources/726 for more
     information on VMware security best practices.

II Service Console package security updates

a. Updated Samba package

    An issue where attackers on the service console management
    network can cause a stack-based buffer overflow in the
    reply_netbios_packet function of nmbd in Samba. On systems
    where Samba is being used as a WINS server, exploiting this
    vulnerability can allow remote attackers to execute arbitrary
    code via crafted WINS Name Registration requests followed by a
    WINS Name Query request.

    An issue where attackers on the service console management
    network can exploit a vulnerability that occurs when Samba is
    configured as a Primary or Backup Domain controller. The
    vulnerability allows remote attackers to have an unknown impact
    via crafted GETDC mailslot requests, related to handling of
    GETDC logon server requests.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the names CVE-2007-5398 and CVE-2007-4572 to these
    issues.

Note: By default Samba is not configured as a WINS server or a domain
controller and ESX is not vulnerable unless the administrator
has changed the default configuration.

    This vulnerability can be exploited remotely only if the
    attacker has access to the service console network.

    Security best practices provided by VMware recommend that the
    service console be isolated from the VM network. Please see
    http://www.vmware.com/resources/techresources/726 for more
    information on VMware security best practices.

    RPM Updated:
    samba-3.0.9-1.3E.14.1vmw

    samba-common-3.0.9-1.3E.14.1vmw

    VM Shutdown: Yes

b. Updated util-linux package

    The patch addresses an issue where the mount and umount
    utilities in util-linux call the setuid and setgid functions in
    the wrong order and do not check the return values, which could
    allow attackers to gain elevated privileges via helper
    application such as mount.nfs.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2007-5191 to this issue.

    RPM Updated:
    util-linux-2.11y-31.24vmw
    losetup-2.11y-31.24vmw

    http://kb.vmware.com/kb/1002972

c. Updated Perl package

    The update addresses an issue where the regular expression
    engine in Perl can be used to issue a specially crafted regular
    expression that allows the attacker to run arbitrary code with
    the permissions level of the current Perl user.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2007-5116 to this issue.

    RPM Updated:
    perl-5.8.0-97.EL3

    http://kb.vmware.com/kb/1002964

d. Updated OpenSSL package

    A flaw in the SSL_get_shared_ciphers() function can allow an
    attacker to cause a buffer overflow problem by sending ciphers

    to applications that use the function.

    A possible vulnerability that would allow a local attacker to
    obtain private RSA keys being used on a system using the OpenSSL
    package.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the names CVE-2007-3108, and CVE-2007-5135 to these
    issues.
