3. Problem description:

~ I   Updated aacraid driver

~        This patch fixes a flaw in how the aacraid SCSI driver checked
~        IOCTL command permissions.  This flaw might allow a local user
~        on the service console to cause a denial of service or gain
~        privileges. Thanks to Adaptec for reporting this issue.

~        The Common Vulnerabilities and Exposures project (cve.mitre.org)
~        has assigned the name CVE-2007-4308 to this issue.

~        ESX Server 2.5.4 Upgrade Patch 15
~        ESX Server 2.5.5 Upgrade Patch 4

~        RPM Updated:
~        VMware-esx-drivers-scsi-aacraid_esx30.rpm
~        kernel-vmnix.rpm

~        VM Shutdown: Yes
~        Host Reboot: Yes

~ II  Service Console package security updates

~     a. Samba

~        Alin Rad Pop of Secunia Research found a stack buffer overflow
~        flaw in the way Samba authenticates remote users.  A remote
~        unauthenticated user could trigger this flaw to cause the Samba
~        server to crash or to execute arbitrary code with the
~        permissions of the Samba server.

~        Note: This vulnerability can be exploited only if the attacker
~              has access to the service console network.  The Samba
~              client is installed by default in the service console, but
~              the Samba server is not.

~        The Common Vulnerabilities and Exposures project (cve.mitre.org)
~        has assigned the name CVE-2007-6015 to this issue.

~        RPM Updated:
~        samba-3.0.9-1.3E.14.3.i386.rpm,
~        samba-client-3.0.9-1.3E.14.3.i386.rpm,
~        samba-common-3.0.9-1.3E.14.3.i386.rpm

~        VM Shutdown: No
~        Host Reboot: No

~        ESX Server 3.0.2 ESX-1003359
~        http://download3.vmware.com/software/vi/ESX-1003359.tgz
~        md5sum: c1fc3232c76aea150308b2227d9d522e
~        http://kb.vmware.com/kb/1003359

~        ESX Server 3.0.1 ESX-1003347
~        http://download3.vmware.com/software/vi/ESX-1003347.tgz

~        ESX Server 2.5.4 Upgrade Patch 15
~        ESX Server 2.5.5 Upgrade Patch 4

~        Deployment Considerations

~        IMPORTANT: The samba-3.0.9-1.3E.14.3vmw RPM is not installed
~        with a default installation of ESX Server software, but some
~        customers choose to install the Samba application on their
~        hosts. VMware recommends against installing such applications in
~        the console operating system, but in order to provide a
~        complete fix to this security issue, this patch supplies the
~        samba-3.0.9-1.3E.14.3vmw RPM. Applying this patch will install
~        the RPM while updating the samba-client-3.0.9-1.3E.14.3vmw and
~        samba-common-3.0.9-1.3E.14.3vmw RPMs, which are part of a
~        default ESX Server software installation. To exclude the
~        samba-3.0.9-1.3E.14.3vmw RPM when installing this bundle, use
~        the exclude option for the esxupdate utility as follows:

~            esxupdate -d <DepotURL> -x samba-3.0.9-1.3E.14.3vmw update

~        Here, <DepotURL> is the URL of the depot from which you are
~        installing your bundles. See the ESX Server 3 Patch Management
~        Guide for more information on advanced options for the esxupdate
~        utility.

~     b. Python

~        Chris Evans of the Google security research team discovered an
~        integer overflow issue with the way Python's Perl-Compatible
~        Regular Expression (PCRE) module handled certain regular
~        expressions.  If a Python application used the PCRE module to
~        compile and execute untrusted regular expressions, it might be
~        possible to cause the application to crash, or to execute
~        arbitrary code with the privileges of the Python interpreter.

~        The Common Vulnerabilities and Exposures project (cve.mitre.org)
~        has assigned the name CVE-2006-7228 to this issue.

~        Piotr Engelking discovered a flaw in Python's locale module
~        where strings generated by the strxfrm() function were not
~        properly NUL-terminated.  This might result in disclosure of
~        data stored in the memory of a Python application using the
~        strxfrm() function.

~        The Common Vulnerabilities and Exposures project (cve.mitre.org)
~        has assigned the name CVE-2007-2052 to this issue.

~        Slythers Bro reported multiple integer overflow flaws in
~        Python's imageop module.  These could allow an attacker to cause
~        a Python application to crash, enter an infinite loop, or
~        possibly execute arbitrary code with the privileges of the
~        Python interpreter.

~        The Common Vulnerabilities and Exposures project (cve.mitre.org)
~        has assigned the name CVE-2007-4965 to this issue.

~        RPM Updated:
~        python-2.2.3-6.8.i386.rpm

~        VM Shutdown: Yes
~        Host Reboot: Yes
