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)

represent large numbers. An attacker could exploit this and cause a denial
of service. This issue only affected Ubuntu 9.10. (CVE-2009-1904)");
