Red Hat, Inc. Red Hat Security Advisory
Synopsis: New util-linux packages available to fix /bin/login pam problem
Advisory ID: RHSA-2001:132-04
Issue date: 2001-10-11
Updated on: 2001-10-16
Product: Red Hat Linux
Keywords: login pam pam_limits
Cross references:
Obsoletes: RHSA-2001:095-04
---------------------------------------------------------------------
1. Topic:
New util-linux packages are available that fix a problem with /bin/login's
PAM implementation. This could, in some non-default setups, cause users to
receive credentials of other users. It is recommended that all users
update to the fixed packages.
2001-10-22: Packages are now available for Red Hat Linux 7.2. Notably,
these packages also fix the problem noted in RHSA-2001:095-04 (vipw
incorrectly setting permissions on some files) - this bug was accidentally
reintroduced in Red Hat Linux 7.2.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386
3. Problem description:
A problem existed in /bin/login's PAM implementation; it stored the value
of a static pwent buffer across PAM calls; when used with some PAM modules
in non-default configuration (such as pam_limits), it would overwrite the
buffer, causing a user to get credentials of another user.
Thanks go to Tarhon-Onu Victor <mituc@ac.tuiasi.ro> for bringing the
problem to our attention, and to Olaf Kirch <okir@caldera.de> for providing
the patch.
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.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
51646 - pam limits drops other user privileges
6. RPMs required:

You can verify each package with the following command:
rpm --checksig <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg <filename>

1. Topic:
New squid packages are available that fix a potential DoS in Squid's FTP
handling code. It is recommened that squid users update to the fixed
packages.
The packages for Red Hat Linux 6.2 also fix the problem described in
RHSA-2001:097-04; it was later discovered that Red Hat Linux 6.2 is
vulnerable to the same problem in accelerator-only mode.
2001-10-22: Packages are now available for Red Hat Linux 7.2.
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
3. Problem description:
Certain FTP requests could cause the Squid daemon to abort, making it
unavailable for a period of seconds. If enough of these requests are sent
in a short period of time, the Squid daemon will not be restarted.
Thanks go to Vladimir Ivaschenko for bringing this to our attention, and
to Henrik Nordstrom and the Squid team for providing a fix.
