Stack-based buffer overflow in BitchX 1.1 Final allows remote IRC
servers to execute arbitrary code via a long string in a MODE command,
related to the p_mode variable.

Nico Golde reports :

There is a security issue in ircii-pana in bitchx' hostname command.
The e_hostname function (commands.c) uses tmpnam to create a temporary
file which is known to be insecure.

Chris reports :

Chris has reported a vulnerability in the Cypress script for BitchX,
which can be exploited by malicious people to disclose potentially
sensitive information or to compromise a vulnerable system.

The vulnerability is caused due to malicious code being present in the
modules/mdop.m file. This can be exploited to disclose the content of
various system files or to execute arbitrary shell commands.

Successful exploitation allows execution of arbitrary code, but
requires the control of the 'lsyn.webhop.net' domain."

(BitchX: Multiple vulnerabilities)

    bannedit reported a boundary error when handling overly long IRC MODE
    messages (CVE-2007-4584). Nico Golde reported an insecure creation of a
    temporary file within the e_hostname() function (CVE-2007-5839).
  
Impact :

    A remote attacker could entice a user to connect to a malicious IRC
    server, resulting in the remote execution of arbitrary code with the
    privileges of the user running the application. A local attacker could
    perform symlink attacks to overwrite arbitrary files on the local
    machine.
  
Workaround :

    There is no known workaround at this time."
