Synopsis: Updated zip package fixes security issue
Advisory ID: FLSA:2255
Issue date: 2005-02-01
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2255
CVE Names: CAN-2004-1010
---------------------------------------------------------------------

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

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

The zip program is an archiving utility which can create ZIP-compatible
archives.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

A buffer overflow bug has been discovered in zip when handling long file
names. An attacker could create a specially crafted path which could
cause zip to crash or execute arbitrary instructions. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CAN-2004-1010 to this issue.

Users of zip 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.

Updated unarj package fixes security issue
---------------------------------------------------------------------
Fedora Legacy Update Advisory

Synopsis: Updated unarj package fixes security issue
Advisory ID: FLSA:2272
Issue date: 2005-02-01
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2272
CVE Names: CAN-2004-0947 CAN-2004-1027
---------------------------------------------------------------------
1. Topic:

An updated unarj package that fixes a buffer overflow vulnerability and
a directory traversal vulnerability is now available.

The unarj program is an archiving utility which can extract
ARJ-compatible archives.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

A buffer overflow bug was discovered in unarj when handling long file
names contained in an archive. An attacker could create a specially
crafted archive which could cause unarj to crash or possibly execute
arbitrary code when extracted by a victim. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0947 to this issue.

Additionally, a path traversal vulnerability was discovered in unarj. An
attacker could create a specially crafted archive which would create
files in the parent ("..") directory when extracted by a victim. When
used recursively, this vulnerability could be used to overwrite critical
system files and programs. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-1027 to this
issue.

Users of unarj should upgrade to this updated package which contains
backported patches and is not vulnerable to 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]
