RHSA-2003:372 - Security Advisory
Security Advisory: Low
Updated wget packages that correct a buffer overrun are now available.
GNU Wget is a file-retrieval utility that uses the HTTP and FTP protocols.
A buffer overflow in the url_filename function for wget 1.8.1 allows
attackers to cause a segmentation fault via a long URL. Red Hat does not
believe that this issue is exploitable to allow an attacker to be able to
run arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2002-1565 to this issue.
Users of wget should install the erratum package, which contains a
backported security patch and is not vulnerable to this issue.
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
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:
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

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:
