Description :

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.

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.

that represent large numbers. An attacker could exploit this and cause
a denial of service. This issue only affected Ubuntu 9.10.
