Trustix Secure Linux Security Advisory #2002-0056

Package name:      apache
Summary:           Remote DoS attack
Date:              2002-06-19
Affected versions: TSL 1.01, 1.1, 1.2, 1.5

- --------------------------------------------------------------------------

Problem description:
  From the original Apache advisory:

    Versions of the Apache web server up to and including 1.3.24 and 2.0
    up to and including 2.0.36 contain a bug in the routines which deal
    with invalid requests which are encoded using chunked encoding.  This
    bug can be triggered remotely by sending a carefully crafted invalid
    request.
 
  On TSL, this can be used in a denial of service attack but is not belived
  to be exploitable in any other manner.

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

  Users of TSL 1.01, 1.1 and 1.2 may want to read the file
