RHSA-2003:030 - Security Advisory

Topic

Updated Lynx packages fix an error in the way Lynx parses its command line
arguments which can lead to faked headers being sent to a Web server.

Description

Lynx is a character-cell Web browser, suitable for running on terminals
such as the VT100.

Lynx constructs its HTTP queries from the command line (or WWW_HOME
environment variable) without regard to special characters such as carriage
returns or linefeeds. When given a URL containing such special characters,
extra headers could be inserted into the request. This could cause scripts
using Lynx to fetch data from the wrong site from servers with virtual hosting.

Users of Lynx are advised to upgrade to these erratum packages which
contain a patch to correct this isssue.

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.
