Security Advisory Updated nss_ldap packages fix pam_ldap vulnerability

Advisory: RHSA-2002:084-22
Type: Security Advisory
Severity: N/A
Issued on: 2002-05-07
Last updated on: 2002-06-04
Affected Products: Red Hat Linux 6.2
Red Hat Linux 7.0
Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3
CVEs (cve.mitre.org): CVE-2002-0374

Details

Updated nss_ldap packages are now available for Red Hat Linux 6.2, 7,
7.1, 7.2, and 7.3. These packages fix a string format vulnerability in the
pam_ldap module.

[Update Jun 4, 2002]
Replacement packages have been added for Red Hat Linux 6.2. The previous
packages could not be installed with the version of RPM that shipped with
Red Hat Linux 6.2

The pam_ldap module provides authentication for user access to a system by
consulting a directory using LDAP. Versions of pam_ldap prior to version
144 include a format string bug in the logging function. The packages
included in this erratum update pam_ldap to version 144, fixing this bug.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0374 to this issue.

Due to differences in the default behavior of the pam_ldap module when
performing account management, the version of authconfig included in Red
Rat Linux 7.2 generates incorrect /etc/pam.d/system-auth files for
the version of pam_ldap included in this erratum. Thus, an updated
version of authconfig for Red Hat Linux 7.2 is included in this erratum
(versions of authconfig included with Red Hat Linux 7, 7.1, and 7.3 are not
affected).

Our thanks go to the pam_ldap team at padl.com for bringing this to our
attention.

A previous revision of this erratum included packages which could not be
installed with the version of RPM included with Red Hat Linux 6.2. While
they can be installed with versions of RPM which have been released as
errata for Red Hat Linux 6.2, this revision includes packages which remove
this restriction. Packages for Red Hat Linux 7, 7.1, 7.2, and 7.3 have not
been modified.


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.
