1. Summary:

An updated Pine package is now available for Red Hat Enterprise Linux 2.1
to fix a denial of service attack.

2. Relevant releases/architectures:

3. Problem description:

Pine is an email user agent.

The c-client IMAP client library, as used in Pine 4.44 contains an integer
overflow and integer signedness flaw.  An attacker could create a malicious
IMAP server in such a way that it would cause Pine to crash.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
 CAN-2003-0297 to this issue.

Users of Pine are advised to upgrade to these erratum packages which
contain a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date
