"Emmanouel Kellinis discovered that Ruby did not properly handle
certain 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 represent large numbers. An attacker could exploit this and cause
a denial of service. This issue only affected Ubuntu 9.10.
(CVE-2009-1904).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
