Synopsis:          Updated pine packages are available
Advisory ID:       RHSA-2002:009-06

Obsoletes:         RHSA-2001:042
---------------------------------------------------------------------

1. Topic:

Pine (version 4.43 and earlier) as released with all currently
supported versions of Red Hat Linux (6.2, 7, 7.1, 7.2), contains a URL
handling bug. This bug can allow a malicious attacker to cause arbitrary
commands embedded in a URL to be executed on the users system upon
attempting to view the URL.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, sparc

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

3. Problem description:

The purpose of this release is to fix a security bug with the
treatment of quotes in the URL-handling code. The bug allows a
malicious sender to embed commands in a URL. This bug is present
in all versions of UNIX Pine 4.43 or earlier.

Example: A URL constructed as:

http://www.somewhere.com/'&touch${IFS}/tmp/foo${IFS}/tmp/bar'

would cause the files /tmp/foo and /tmp/bar to be created on the
user's machine if the URL is viewed.

Thanks to zen-parse for discovering and reporting this problem.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0014 to this issue.

All users of Pine are urged to upgrade to this erratum release.

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 Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
