Subject: [FLSA-2005:158801] Updated bzip2 packages fix
security issues
---------------------------------------------------------------------
Fedora Legacy Update Advisory
Synopsis: Updated bzip2 packages fix security issues
Advisory ID: FLSA:158801
Issue date: 2005-11-14
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CVE-2005-0758 CVE-2005-0953 CVE-2005-1260
---------------------------------------------------------------------
---------------------------------------------------------------------
1. Topic:
Updated bzip2 packages that fix multiple issues are now available.
Bzip2 is a data compressor.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386
3. Problem description:
A bug was found in the way bzgrep processes file names. If a user can be
tricked into running bzgrep on a file with a carefully crafted file
name, arbitrary commands could be executed as the user running bzgrep.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-0758 to this issue.
A bug was found in the way bzip2 modifies file permissions during
decompression. If an attacker has write access to the directory into
which bzip2 is decompressing files, it is possible for them to modify
permissions on files owned by the user running bzip2 (CVE-2005-0953).
A bug was found in the way bzip2 decompresses files. It is possible for
an attacker to create a specially crafted bzip2 file which will cause
bzip2 to cause a denial of service (by filling disk space) if
decompressed by a victim (CVE-2005-1260).
Users of Bzip2 should upgrade to these updated packages, which contain
backported patches to correct 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.
