(Rootkit Hunter: Insecure temporary file creation)
Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux
Security Team have reported that the check_update.sh script and the

A local attacker could create symbolic links in the temporary
files directory, pointing to a valid file somewhere on the filesystem.
