Date: February 14, 2005
Bugs: #81344
ID: 200502-18
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
VMware may load shared libraries from an untrusted, world-writable directory, resulting in the execution of arbitrary code.
Background
==========
VMware Workstation is a powerful virtual machine for developers and system administrators.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 vmware-workstation < 4.5.2.8848-r5 >= 4.5.2.8848-r5
Description
===========
Tavis Ormandy of the Gentoo Linux Security Audit Team has discovered that VMware Workstation searches for gdk-pixbuf loadable modules in an untrusted, world-writable directory.
Impact
======
A local attacker could create a malicious shared object that would be loaded by VMware, resulting in the execution of arbitrary code with the privileges of the user running VMware.
Workaround
==========
The system administrator may create the file /tmp/rrdharan to prevent malicious users from creating a directory at that location:
# touch /tmp/rrdharan
Resolution
==========
All VMware Workstation users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/vmware-workstation-4.5.2.8848-r5"
Availability
============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:

Concerns?
=========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.

-------------------------------------------------------------------
Description
===========
Max Vozeler discovered that the movemail utility contains several format string errors.
Impact
======
An attacker could set up a malicious POP server and entice a user to connect to it using movemail, resulting in the execution of arbitrary code with the rights of the victim user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Emacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/emacs-21.4"
All XEmacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/xemacs-21.4.15-r3"
