Gentoo Linux Security Advisory GLSA 200711-23 - Multiple vulnerabilities have been discovered in several VMware products. Neel Mehta and Ryan Smith (IBM ISS X-Force) discovered that the DHCP server contains an integer overflow vulnerability, an integer underflow vulnerability and another error when handling malformed packets, leading to stack-based buffer overflows or stack corruption. Rafal Wojtczvk (McAfee) discovered two unspecified errors that allow authenticated users with administrative or login privileges on a guest operating system to corrupt memory or cause a Denial of Service. Another unspecified vulnerability related to untrusted virtual machine images was discovered. Versions less than 6.0.1.55017 are affected.

Synopsis
========

VMware guest operating systems might be able to execute arbitrary code
with elevated privileges on the host operating system through multiple
flaws.

Background
==========

VMware Workstation is a virtual machine for developers and system
administrators. VMware Player is a freeware virtualization software
that can run guests produced by other VMware products.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 vmware-workstation < 6.0.1.55017 *>= 5.5.5.56455
>= 6.0.1.55017
2 vmware-player < 2.0.1.55017 *>= 1.0.5.56455
>= 2.0.1.55017
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.

Description
===========

Multiple vulnerabilities have been discovered in several VMware
products. Neel Mehta and Ryan Smith (IBM ISS X-Force) discovered that
the DHCP server contains an integer overflow vulnerability
(CVE-2007-0062), an integer underflow vulnerability (CVE-2007-0063) and
another error when handling malformed packets (CVE-2007-0061), leading
to stack-based buffer overflows or stack corruption. Rafal Wojtczvk
(McAfee) discovered two unspecified errors that allow authenticated
users with administrative or login privileges on a guest operating
system to corrupt memory or cause a Denial of Service (CVE-2007-4496,
CVE-2007-4497). Another unspecified vulnerability related to untrusted
virtual machine images was discovered (CVE-2007-5617).

VMware products also shipped code copies of software with several
vulnerabilities: Samba (GLSA-200705-15), BIND (GLSA-200702-06), MIT
Kerberos 5 (GLSA-200707-11), Vixie Cron (GLSA-200704-11), shadow
(GLSA-200606-02), OpenLDAP (CVE-2006-4600), PAM (CVE-2004-0813,
CVE-2007-1716), GCC (CVE-2006-3619) and GDB (CVE-2006-4146).

Impact
======

Remote attackers within a guest system could possibly exploit these
vulnerabilities to execute code on the host system with elevated
privileges or to cause a Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All VMware Workstation users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=app-emulation/vmware-workstation-5.5.5.56455"

All VMware Player users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=app-emulation/vmware-player-1.0.5.56455"
