Fedora Legacy Update Advisory

Synopsis: Updated unzip package fixes security issue
Advisory ID: FLSA:180159
Issue date: 2006-04-04
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix, Security
CVE Names: CVE-2005-4667
---------------------------------------------------------------------



---------------------------------------------------------------------
1. Topic:

An updated unzip package that fixes a buffer overflow vulnerability is
now available.

The unzip utility is used to list, test, or extract files from a zip
archive.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386
Fedora Core 3 - i386, x86_64

3. Problem description:

A buffer overflow bug has been discovered in unzip when handling long
file names. An attacker could create a specially crafted path which
could cause unzip to crash or execute arbitrary instructions. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2005-4667 to this issue.

Users of unzip should upgrade to this updated package, which contains
backported patches and is not vulnerable to this issue.

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.
