Synopsis
========
Multiple vulnerabilities in BitchX may allow for the remote execution
of arbitrary code or symlink attacks.
Background
==========
BitchX is an IRC client.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-irc/bitchx <= 1.1-r4 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
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Since BitchX is no longer maintained, we recommend that users unmerge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"
