mailscanner 4.55.10 and other versions before 4.74.16-1 might allow local users to overwrite arbitrary files via a symlink attack on certain temporary files used by the (1) f-prot-autoupdate, (2) clamav-autoupdate, (3) panda-autoupdate.new, (4) trend-autoupdate.new, and (5) rav-autoupdate.new scripts in /etc/MailScanner/autoupdate/, a different vulnerability than CVE-2008-5140.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
