Title
=====

Two Debian Security Advisories:

1. DSA 1203-1 - New libpam-ldap packages fix access control bypass

2. DSA 1204-1 - New ingo1 packages fix arbitrary shell command execution

Detail
======

1. Steve Rigler discovered that the PAM module for authentication against
LDAP servers processes PasswordPolicyReponse control messages incorrectly,
which might lead to an attacker being able to login into a suspended
system account.

2. It was discovered that the Ingo email filter rules manager performs 
insufficient escaping of user-provided data in created procmail rules
files, which allows the execution of arbitrary shell commands.

Package        : libpam-ldap
Vulnerability  : programming error
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2006-5170
Debian Bug     : 392984

Steve Rigler discovered that the PAM module for authentication against
LDAP servers processes PasswordPolicyReponse control messages incorrectly,
which might lead to an attacker being able to login into a suspended
system account.

For the stable distribution (sarge) this problem has been fixed in
version 178-1sarge3. Due to technical problems with the security
buildd infrastructure this update lacks a build for the Sun Sparc
architecture. It will be released as soon as the problems are resolved.

For the unstable distribution (sid) this problem has been fixed in
version 180-1.2.

We recommend that you upgrade your libpam-ldap package.


Upgrade Instructions
- - --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
