The at utility in Solaris has name handling and race condition vulnerabilities. Using the -r switch to remove a job allows an attacker to remove any file on the filesystem as root. Although at filters out absolute paths, a simple ../ directory traversal maneuver allows an attacker to remove files out of the allowed boundary.
