Apple Safari fails to properly handle archive files that contain symbolic links, which may allow a remote, unauthenticated attacker to execute arbitrary code.
Symbolic links are references to files and folders.
By default, Safari will automatically open "safe" file types, such as pictures, movies, and archive files, including ZIP files. If the contents of an archive file are also considered safe, then Safari will automatically open the contents after the archive is extracted.
Safari can automatically execute the symbolic link target when it is automatically extracted.
A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
Apply an update
Apply Apple Security Update 2006-003. With this update, Safari will not resolve downloaded symbolic links.
Disable "Open 'safe' files after downloading"
Disable the option "Open 'safe' files after downloading," as specified in the Securing Your Web Browser document. This will help prevent automatic exploitation of this and other vulnerabilities.
