McAfee Inc. has repaired a flaw in its antivirus program for Mac OS X machines that attackers could exploit to...
bypass the malware scanner and gain elevated system privileges.
"The vulnerability is caused due to /Library/Application Support/Virex/VShieldExclude.txt having insecure permissions and being created insecurely," Danish vulnerability clearinghouse Secunia said in an advisory. "This can be exploited to create arbitrary files with escalated privileges via symlink attacks."
McAfee recommends that users apply the patch, which has been pushed to all its live update servers.
