Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated nss_ldap packages fix pam_ldap vulnerability
Advisory ID: RHSA-2002:084-17
Issue date: 2002-05-07
Updated on: 2002-05-26
Product: Red Hat Linux
Keywords: pam_ldap format string syslog security
Cross references:
Obsoletes: RHSA-2000:024
CVE Names: CAN-2002-0374
- ---------------------------------------------------------------------
1. Topic:
Updated nss_ldap packages are now available for Red Hat Linux 6.2, 7.0,
7.1,7.2, and 7.3. These packages fix a string format vulnerability in the
pam_ldap module.
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
Red Hat Linux 7.3 - i386
3. Problem description:
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
Hat Linux 7.2 will generate incorrect /etc/pam.d/system-auth files for this
version of pam_ldap. This update includes an updated version of
authconfig for Red Hat Linux 7.2 which addresses this problem (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.
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.
