Advisory ID: FLSA:1232
Issue date: 2004-02-11
Product: Red Hat Linux
Keywords: Security
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1232

1. Topic:

Updated slocate packages are now available that fix security
vulnerabilities which may allow local users to gain “slocate” group
privileges.

2. Relevant releases/architectures:

Red Hat Linux 7.2 – i386
Red Hat Linux 7.3 – i386
Red Hat Linux 8.0 – i386

3. Problem description:

Slocate is a security-enhanced version of locate, designed to
find files on a system via a central database.

A vulnerability has been found in Slocate versions up to and
including 2.7 where a carefully crafted database could overflow a
heap-based buffer. A local user could exploit this vulnerability to
gain “slocate” group privileges and then read the entire slocate
database. The Common Vulnerabilities and Exposures project
(cve.mitre.org/) has assigned
the name CAN-2003-0848 to this issue.

These packages also fix a buffer overflow that affected
unpatched versions of Slocate prior to 2.7. This vulnerability
could also allow a local user to gain “slocate” group privileges.
The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name
CAN-2003-0056 to this issue.

Users of slocate should update to these update packages, which
contain a backported security patch that corrects this issue.

Fedora Legacy would like to thank Patrik Hornik and Kevin
Lindsay fir disclosing these issues, as well as Michael Schwendt
for providing a backported fix for Red Hat Linux 7.2, 7.3, and
8.0.

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 yum and apt.
Many people find this an easier way to apply updates. To use yum
issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that
you have yum or apt-get configured for obtaining Fedora Legacy
content. Please visit http://www.fedoralegacy.org/download
for directions on how to configure yum and apt-get.
