Fedora Legacy Update Advisory
Synopsis: Updated ruby package fixes security issues
Advisory ID: FLSA:152768
Issue date: 2005-05-12
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CAN-2004-0755 CAN-2004-0983
---------------------------------------------------------------------
---------------------------------------------------------------------
1. Topic:
An updated ruby package that fixes security issues is now available.
Ruby is an interpreted scripting language for object-oriented
programming.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
3. Problem description:
A flaw was discovered in the CGI module of Ruby. If empty data is sent
by the POST method to the CGI script which requires MIME type
multipart/form-data, it can get stuck in a loop. A remote attacker could
trigger this flaw and cause a denial of service. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CAN-2004-0983 to this issue.
Andres Salomon reported an insecure file permissions flaw in the CGI
session management of Ruby. FileStore created world readable files that
could allow a malicious local user the ability to read CGI session data.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0755 to this issue.
Users are advised to upgrade to this erratum package, which contains
backported patches fixing these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.
Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
