RHBA-2005:549 - Bug Fix Advisory
Synopsis
pam bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated pam packages that resolve bugs in a PAM library are now available.
Description
PAM (Pluggable Authentication Modules) is a system security library that
allows system administrators to set authentication policies without having
to recompile programs that handle authentication.
The Expect scripting language is a tool primarily for automating
interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip,
etc. Applications such as passwd which use the conversation function
provided by PAM may work incorrectly when invoked from expect scripts.
Previously, when a user logged in from a console and was the first such
user, the console locked. When the X server crashed or was killed by the
user with the [Ctrl]-[Alt]-[BkSp] key combination, the console lock was not
released. Subsequent logins via a console did not obtain the lock.
If the passwd command was issued on a NIS master server it did not change
the password.
All users of PAM should upgrade to these updated packages, which resolve
these issues.
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.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
