string operations. An attacker could exploit this issue and possibly
execute arbitrary code with application privileges. (CVE-2009-4124)

Giovanni Pellerano, Alessandro Tanasi, and Francesco Ongaro discovered that
Ruby did not properly sanitize data written to log files. An attacker could
insert specially-crafted data into log files which could affect certain
terminal emulators and cause arbitrary files to be overwritten, or even
possibly execute arbitrary commands. (CVE-2009-4492)

It was discovered that Ruby did not properly handle string arguments that
