Subject: CVE-2007-5226 remote denial of service

Date: Mon, 8 Oct 2007 23:55:20 +0200

[Message part 1 (text/plain, inline)]

Package: dircproxy
Version: 1.0.5-3
Severity: grave
Tags: security

Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for dircproxy.

CVE-2007-5226[0]:
| irc_server.c in dircproxy 1.2.0 and earlier allows remote attackers to
| cause a denial of service (segmentation fault) via an ACTION command
| without a parameter, which triggers a NULL pointer dereference, as
| demonstrated using a blank /me message from irssi.

If you fix this vulnerability please also include the CVE id
in your changelog entry.

The null pointer dereference itself is not that big kind of 
a problem here but since this also means to lose the data 
you want to read while you are away I mark this as grave.

For further information:
[0] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5226

Kind regards
Nico

I don't think this warrants a DSA, feel free to fix it through a
stable point release.
