3. Problem description: Problems addressed by these patches: I Arbitrary code execution and denial of service vulnerabilities
This release fixes a security vulnerability that could allow a
guest operating system user with administrative privileges to cause
memory corruption in a host process, and thus potentially execute
arbitrary code on the host. (CVE-2007-4496)
This release fixes a denial of service vulnerability that could
allow a guest operating system to cause a host process to become
unresponsive or exit unexpectedly. (CVE-2007-4497)
Thanks to Rafal Wojtczvk of McAfee for identifying and reporting
these issues.
ESX
II Hosted products DHCP security vulnerabilities addressed
This release fixes several vulnerabilities in the DHCP server
that could enable a specially crafted packets to gain system-level
privileges. (CVE-2007-0061, CVE-2007-0062, CVE-2007-0063)
Thanks to Neel Mehta and Ryan Smith of the IBM Internet Security
Systems X-Force for discovering and researching these
vulnerabilities.
Hosted products
IV Escalation of privileges on Windows hosted systems
This release fixes a security vulnerability in which Workstation
was starting registered Windows services in an insecure manner.
This vulnerability could allow a malicious user to escalate user
privileges.
Thanks to Foundstone for discovering this vulnerability.
Hosted products
V Potential denial of service using VMware Player
This release fixes a problem that prevented VMware Player from
launching. This problem was accompanied by the error message VMware
Player unrecoverable error: (player) Exception 0xc0000005 (access
violation) has occurred.
Hosted products
VI ESX Service Console updates
Various bugs were found in NDR parsing, used to decode MS-RPC
requests in Samba. A remote attacker could have sent carefully
crafted requests causing a heap overflow, which may have led to the
ability to execute arbitrary code on the server. (CVE-2007-2446)
Unescaped user input parameters were being passed as arguments to
/bin/sh. A remote, authenticated, user could have triggered this
flaw and executed arbitrary code on the server. Additionally, this
flaw could be triggered by a remote unauthenticated user if Samba
was configured to use the non-default username map script option.
(CVE-2007-2447)
Thanks to the Samba developers, TippingPoint, and iDefense for
identifying and reporting these issues.
Note: These issues only affect the service console network, and are
not remote vulnerabilities for ESX Server hosts that have been set
up with the security best practices provided by VMware.

c. This patch provides updated service console package krb5 update.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
assigned the names CVE-2007-2442, CVE-2007-2443, and CVE-2007-2798
to these security issues.
Thanks to Wei Wang of McAfee Avert Labs discovered these
vulnerabilities.
Note: The VMware service console does not provide the kadmind
binary, and is not affected by these issues, but a update has been
provided for completeness.
ESX
d. Service console update for vixie-cron
This patch provides an updated service console package vixie-cron.
Cron is a standard UNIX daemon that runs specified programs at
scheduled times.
A denial of service issue was found in the way vixie-cron verified
crontab file integrity. A local user with the ability to create a
hardlink to /etc/crontab could potentially prevent vixie-cron from
executing certain system cron jobs. (CVE-2007-1856)
Thanks to Raphael Marichez for identifying this issue.
ESX
e. Service console update for shadow-utils
This patch provides an updated shadow-utils package. A new
user's mailbox, when created, could have random permissions for a
short period. This could enable a local malicious user to
read or modify the mailbox. (CVE-2006-1174)
ESX
f. Service console update for OpenLDAP
This patch provides a updated OpenLDAP package. A flaw could
allow users with selfwrite access to modify the distinguished
name of any user, instead of being limited to modify only
their own distinguished name. (CVE-2006-4600)
ESX
g. Service console update for PAM
This patch provides an updated PAM package A vulnerability was
found that could allow console users with access to certain device
files to cause damage to recordable CD drives. Certain file
permissions have now been modified to disallow access.
(CVE-2004-0813)
A flaw was found with console device permissions. It was possible
for various console devices to retain ownership of the previoius
console user after logging out, which could result in leakage of
information to an unauthorized user. (CVE-2007-1716)
ESX
h. Service console update for GCC
This patch provides security fixes for the service console GNU
Compiler Collection (GCC) packages that include C, C++, Java,
Fortran 77, Objective C, and Ada 95 GNU compilers and related
support libraries.
A flaw was found in the fastjar utility that could potentially
allow a malicious user to create a JAR file which, if unpacked
using fastjar, could write to any file that an authorized user had
write access to. (CVE-2006-3619)
Thanks to Jürgen Weigert for identifying this issue.
ESX
i. Service Console update for GDB
This patch provides a security fix for the service console GNU
debugger (GDB). Various vulnerabilities were found in GDB. These
vulnerabilities may allow a malicious user to deceive a user into
loading debugging information into GDB, enabling the execution of
arbitrary code with the privileges of the user. (CVE-2006-4146)
