Description:
Kevin Finisterre has reported a vulnerability in McAfee Virex, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to /Library/Application Support/Virex/VShieldExclude.txt having insecure permissions (world writable) and being created insecurely. This can be exploited to create arbitrary files with escalated privileges via symlink attacks.
The vulnerability is reported in version 7.7. Other versions may also be affected.
Solution:
McAfee Virex version 7.7 (Build 163):
Apply Virex 77 Patch 1 (see vendor advisory for details).
