3. Problem description
I Updated ESX driver
a. 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.

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,

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.
