BitchX: Multiple vulnerabilities — GLSA 200807-12

Multiple vulnerabilities in BitchX may allow for the remote execution of arbitrary code or symlink attacks.

Affected Packages

net-irc/bitchx on all architectures
Affected versions <= 1.1-r4
Unaffected versions

Background

BitchX is an IRC client.

Description

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.

Resolution

Since BitchX is no longer maintained, we recommend that users unmerge the vulnerable package and switch to another IRC client:

 # emerge --unmerge "net-irc/bitchx"
