runpipe v1.2 with security hole fix

runpipe v1.2 with security hole fix

Post by Christopher Neufel » Wed, 12 Mar 1997 04:00:00


   The latest version of runpipe is available now from sunsite or my FTP
   Runpipe is a daemon/client pair which watches a set of named pipes for
a read or write action on a pipe, and then executes a program on the
other end of the pipe. It is most commonly used to run a program on the
other end of the .plan pipe, so that when a person fingers the account,
the .plan "file" appears to contain the output of the program. This can
be used to make plan files which change whenever they're read, or which
deliver different messages depending on other information such as time of
day or whether or not the user is logged on.

   This release fixes a potentially serious security bug in the daemon
when run in system mode, and a potentially annoying behaviour when run in
paranoid mode. I strongly recommend that nobody who runs the daemon in
system mode run it with a version prior to 1.2.

   Here is the .lsm:

1. ANNOUNCE Apache::ASP v1.95 - Examples Security Hole Fixed

ANNOUNCE Apache::ASP v1.95 - Examples Security Hole Fixed

Apache::ASP < > had a security
hole in its ./site/eg/source.asp distribution examples file,
allowing a malicious hacker to potentially write to files in
the directory local to the source.asp example script.

The next version of Apache::ASP v1.95 going to CPAN will not
have this security hole in its example ./site/eg/source.asp
The general CHANGES for this release is below.  Note that
CPAN may not have the 1.95 version for another 24 hours.

Until you have the latest examples, I would recommend deleting
this source.asp file from any public web server that has
Apache::ASP installed on it.

The original report on a similar perl open() bug was at ZDNet's eWeek
where a hacking contest at turned up a bug on
its minivend ecommerce software.

--Joshua Chamas

=item $VERSION = 1.95; $DATE="07/10/00";


 --FIXED: distribution example ./site/eg/source.asp now parses
  out special characters of the open() call when reading local

  This bug would allow a malicious user possible writing
  of files in the same directory as the source.asp script.  This
  writing exploit would only have effect if the web server user
  has write permission on those files.

  Similar bug announced by for minivend software
  in story at:,11011,2600258,00.html


 -$0 now set to transferred file, when using $Server->Transfer

 -Fix for XMLSubsMatch parsing on cases with 2 or more args passed
  to tag sub that was standalone like
    <Apps:header type="header" title="Moo" foo="moo" />
