RHEL 4 / 5 : ruby (RHSA-2008:0561)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated ruby packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

Ruby is an interpreted scripting language for quick and easy
object-oriented programming.

Multiple integer overflows leading to a heap overflow were discovered
in the array- and string-handling code used by Ruby. An attacker could
use these flaws to crash a Ruby application or, possibly, execute
arbitrary code with the privileges of the Ruby application using
untrusted inputs in array or string operations. (CVE-2008-2376,
CVE-2008-2662, CVE-2008-2663, CVE-2008-2725, CVE-2008-2726)

It was discovered that Ruby used the alloca() memory allocation
function in the format (%) method of the String class without properly
restricting maximum string length. An attacker could use this flaw to
crash a Ruby application or, possibly, execute arbitrary code with the
privileges of the Ruby application using long, untrusted strings as
format strings. (CVE-2008-2664)

Red Hat would like to thank Drew Yao of the Apple Product Security
team for reporting these issues.

Users of Ruby should upgrade to these updated packages, which contain
a backported patch to resolve these issues.
