Red Hat: slocate Heap overflow vulnerability
Summary
Summary
Slocate is a security-enhanced version of locate, designed to find files ona system via a central database.Patrik Hornik discovered a vulnerability in Slocate versions up to andincluding 2.7 where a carefully crafted database could overflow aheap-based buffer. A local user could exploit this vulnerability to gain"slocate" group privileges and then read the entire slocate database. TheCommon Vulnerabilities and Exposures project (cve.mitre.org) has assignedthe name CAN-2003-0848 to this issue.Users of Slocate should upgrade to these erratum packages, which contain apatch from Kevin Lindsay that causes slocate to drop privileges beforereading a user-supplied database.
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:

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