(HP Issues Fix for Linux) Mutt E-mail Client Buffer Overflow May Let Remote Users Cause Arbitary Commands to Be Executed on the Mutt User's Host
SecurityTracker Alert ID:  1003179
SecurityTracker URL:  http://securitytracker.com/id/1003179
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 10 2002
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): mutt-1.2.5 and 1.3.24 and prior releases
Description:   A buffer overflow vulnerability was reported in the Mutt e-mail client that may allow remote users to cause arbitrary commands to be executed by another user's Mutt e-mail client.

It is reported that this vulnerability is remotely exploitable. The bug is apparently due to a one byte buffer overflow. No other details on the vulnerability were provided.

Impact:   A remote user may be able to create an e-mail message that, when viewed by another user with the Mutt client, will cause arbitrary commands to be executed by the Mutt client with the privileges of the user running Mutt.
Solution:   The vendor has released a fix for HP Secure OS for Linux and recommends that customers download the RPMs listed in the following Red Hat Security Advisory:

2002-01-07 mutt (RHSA-2002-003) New mutt packages available to fix security problem

http://www.redhat.com/support/errata/RHSA-2002-003.html

HP notes that to install the security advisory RPMs, use the following sequence of commands:

1. If you use the tripwire product, we recommend that you run a
a consistency check and fix any violations before installing
the security advisory RPM.

tripwire --check --interactive

2. Install the advisory RPM from the root account.

rpm -F <advisory RPM name>

3. Update the tripwire database

tripwire --check --interactive

TEXT





---------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY ADVISORY: #011
    Originally issued: 09 January '02
---------------------------------------------------------------

The information in the following Security Advisory should be acted
upon as soon as possible.  Hewlett-Packard Company will not be
liable for any consequences to any customer resulting from the 
customer's failure to fully implement instructions in this Security 
Advisory as soon as possible.

Because the vulnerability does not require a Hewlett-Packard Secure OS
1.0 patch or re-packaging of the RPM affected by the advisory, the
RPMs have not been produced or tested by Hewlett-Packard.

---------------------------------------------------------------
PROBLEM:  Security vulnerability in mutt's RFC822 address parser.

PLATFORM: Any system running HP Secure OS software for Linux Release 1.0

DAMAGE:   Potential overwrite of arbitrary bytes in memory

SOLUTION: Apply the appropriate RPMs (see section B below)

MANUAL ACTIONS: None

AVAILABILITY: The RPMs are available now.
 ---------------------------------------------------------------
 A. Background

    A problem in mutt's RFC822 address parser means that a carefully
    crafted email message could cause arbitrary bytes in memory to be
    overwritten. This vulnerability can be exploited remotely.   

 B. Fixing the problem

    Hewlett-Packard recommends that customers download the RPMs 
    listed in the following Red Hat Security Advisory:

    2002-01-07 mutt (RHSA-2002-003) New mutt packages available to fix
        security problem 

        http://www.redhat.com/support/errata/RHSA-2002-003.html


    To install the security advisory RPMs, use the following sequence
    of commands:

    1. If you use the tripwire product, we recommend that you run a 
       a consistency check and fix any violations before installing
       the security advisory RPM. 

           tripwire --check --interactive

    2. Install the advisory RPM from the root account.

           rpm -F <advisory RPM name>

    3. Update the tripwire database

           tripwire --check --interactive



    NOTE:
    The rpm -q <package name> command can be used to determine if the
    product is installed. Hewlett-Packard recommends applying the
    security advisory fixes to installed packages only. The -F option
    to the RPM installer will only apply the fix if the package is
    currently installed on the system. Dependent RPMs can be found by
    using the "Find Latest RPMs" search facility at
    http://www.redhat.com/apps/download. To find the latest dependent 
    RPM enter the RPM's name in the "By Keyword" box.
