Sys::Syslog and taint

Sys::Syslog and taint Can't Post


I'm using Sys::Syslog for program logging and I have just started using the taint flag (we are trying to tighten up our code). With this combination Syslog will not work. I'm thinking that it's a perl bug, but I wanted to check before I sent off a bug report. I'm also wondering if there is a way around the problem.

The following is the more detailed info:
I'm running perl 5.00503

This is my test script:

#!/usr/bin/perl -wT
use Sys::Syslog;

$SCRIPT_ID = "testMod.cgi(000)";
print "Content-Type: text/html\n\n";
&openlog($ProcName,"pid,cons,nowait", "local0");
&syslog('', "$SCRIPT_ID-1 Execution begun.");
print "HELLO";

When I run this script I get the 'document contained no data error' and the following message in the error log:

'Cannot get host name of local machine at /usr/lib/perl5/5.00503/Sys/
line 248'

I tracked this down and found that the error is actually being generated from Sys::Hostname.

Everything works fine if I remove the -T flag.

Thanks in advance,
Shane Corgatelli

By the way,

I found an answer to this problem. I'm now using Unix::Syslog rather than Sys::Syslog.
Unix::Syslog works almost the same as Sys::Syslog, so it's easy to make the move.
