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 '' domain.


Update the affected package.
