TITLE:
BitchX "e_hostname()" Insecure Temporary File Creation

SECUNIA ADVISORY ID:
SA27463

VERIFY ADVISORY:
http://secunia.com/advisories/27463/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
BitchX 1.x
http://secunia.com/product/1095/

DESCRIPTION:
A security issue has been reported in BitchX, which can be exploited
by malicious, local users to perform certain actions with escalated
privileges.

The security issue is caused due to the "e_hostname()" function
creating a temporary file insecurely using the "tmpnam()" function
when the user issues the "HOSTNAME" or the "IRCHOST" command. This
can be exploited to overwrite arbitrary files on the local system
with the privileges of the user running BitchX.

The security issue is reported in version 1.1a. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only. Do not use the "HOSTNAME" and
"IRCHOST" commands.
