Red Hat Security Advisory
Synopsis: Low: pam security update
Advisory ID: RHSA-2005:805-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-805.html
Issue date: 2005-10-26
Updated on: 2005-10-26
Product: Red Hat Enterprise Linux
CVE Names: CVE-2005-2977
- - ---------------------------------------------------------------------
1. Summary:
An updated pam package that fixes a security weakness is now available for
Red Hat Enterprise Linux 4.
This update has been rated as having low security impact by the Red Hat
Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
3. Problem description:
PAM (Pluggable Authentication Modules) is a system security tool that
allows system administrators to set an authentication policy without
having to recompile programs that handle authentication.
A bug was found in the way PAM's unix_chkpwd helper program validates user
passwords when SELinux is enabled. Under normal circumstances, it is not
possible for a local non-root user to verify the password of another local
user with the unix_chkpwd command. A patch applied that adds SELinux
functionality makes it possible for a local user to use brute force
password guessing techniques against other local user accounts. The Common
Vulnerabilities and Exposures project has assigned the name CVE-2005-2977 to
this issue.
All users of pam should upgrade to this updated package, which contains
backported patches to correct these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. 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.
5. Bug IDs fixed (http://bugzilla.redhat.com/):
168181 - CVE-2005-2977 unix_chkpwd helper doesn't verify requesting user if SELinux is enabled

Red Hat Security Advisory
Synopsis: Low: fetchmail security update
Advisory ID: RHSA-2005:823-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-823.html
Issue date: 2005-10-26
Updated on: 2005-10-26
Product: Red Hat Enterprise Linux
CVE Names: CVE-2005-3088
- - ---------------------------------------------------------------------
1. Summary:
Updated fetchmail packages that fix insecure configuration file creation is
now available.
This update has been rated as having low security impact by the Red Hat
Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
Fetchmail is a remote mail retrieval and forwarding utility.
A bug was found in the way the fetchmailconf utility program writes
configuration files. The default behavior of fetchmailconf is to write a
configuration file which may be world readable for a short period of time.
This configuration file could provide passwords to a local malicious
attacker within the short window before fetchmailconf sets secure
permissions. The Common Vulnerabilities and Exposures project has assigned
the name CVE-2005-3088 to this issue.
Users of fetchmail are advised to upgrade to these updated packages, which
contain a backported patch which resolves this issue.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. 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.
