Buffer overflow in Cocoa spell checking in AppKit in Apple Mac OS X 10.5.8 allows user-assisted remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted document.

freshclam in ClamAV in Apple Mac OS X 10.5.8 with Security Update 2009-005 has an incorrect launchd.plist ProgramArguments key and consequently does not run, which might allow remote attackers to introduce viruses into the system.
