Trustix Secure Linux Security Advisory #2002-0085

Package name: lynx-ssl
Summary: HTTP headers injection
Date: 2002-12-19
Affected versions: TSL 1.1, 1.2, 1.5

- --------------------------------------------------------------------------
Package description:
Lynx is a text-based Web browser. Lynx does not display any images,
but it does support frames, tables and most other HTML tags. Lynx's
advantage over graphical browsers is its speed: Lynx starts and exits
quickly and swiftly when displaying Web pages.

This SSL patch package for Lynx provides the ability to make use of SSL
over HTTP for secure access to web sites (HTTPS) and over NNTP for secure
access to news servers (SNEWS). SSL is handled transparently, allowing
users to continue accessing web sites and news services from within Lynx
through the same interface for both secure and standard transfers.


Problem description:
Due to insufficient checking for illegal characters, the Lynx-ssl
could be tricked into sending additional HTTP headers in a request.


Action:
We recommend that all systems with this package installed be upgraded.
Please note that if you do not need the functionality provided by this
package, you may want to remove it from your system.
