not sure about the details but at least there's a commit... https://svn.kvirc.de/kvirc/changeset/630
heh, i know the details: Affected product: KVIrc Affected version: tested with latest stable version ( 3.2.0) and a snapshot (3.2.5). Other versions may also be affected. CVE: CVE-2007-2951 SAID: SA25740 (http://secunia.com/advisories/25740/) Credit: Stefan Cornelius, Secunia Research Upstream contacted: CCed to this email. Disclosure date: Preliminary date set to Wed 27th June, 2007 -- Background -- "KVIrc is a free portable IRC client based on the excellent Qt GUI toolkit. KVIrc is being written by Szymon Stefanek and the KVIrc Development Team with the contribution of many IRC addicted developers around the world." -- Details -- KVIrc does not properly handle irc:// (and similar URIs like irc6://) URIs passed via the command line, which can be exploited to inject and execute commands by e.g. tricking a user into opening a specially crafted irc:// URI. Successful exploitation requires that KVIrc is registered as the default handler for irc:// or similar URIs. Example: <HTML> <A HREF="irc://aa:11/lol,${run mkdir /tmp/secunia;};">irc</A> </HTML> Note: This may be dependent upon the browser used. During tests Galeon launched KVIrc without asking for confirmation, on the other hand Konqueror and newer Firefox versions asked the user for confirmation prior to launching KVirc, which mitigates the vulnerability. The vulnerability is caused due to the "parseIrcUrl()" function in src/kvirc/kernel/kvi_ircurl.cpp not properly sanitising parts of the URI when building the command for KVIrc's internal script system. This can be exploited to inject and execute commands for the KVIrc script system (including the "run" command, which can be leveraged to execute shell commands). Credits should be given to: Stefan Cornelius, Secunia Research.
public now. forgot to CC net-irc last time, done that now - please provide fixed ebuilds
Added a svn-snapshotted ebuild, tested with a bunch of scripts and channels, no crashes so far, so I think we're safe.

(In reply to comment #8) > It fails here on x86 with USE=-ipv6, IPv6 enabled works. Re-tested and found the same on amd64. Reverted stabilisation on amd64.
okay, waiting for upstream to provide a fix
Hope it's 3.2.6_pre based since 3.2.5 is b0rked for sparc...
Going back to ebuild...
the patch is a 2-liner or so. backporting it should work?
Yeah but the old version breaks for firsttime users as the setup wizard there caused segv's... So we really need a fully working version now. I'd even prefer enabling ipv6 by default to get this version. net-irc: opinions?
If this vuln if so important i don't see a reason why we can't force ipv6, since ipv6 is enabled by default on all the profiles. So, okay for me
net-irc, what's the status here?
ok, now that the ipv6 issue is fixed, we should be good to go. Arches, please test and mark stable net-irc/kvirc-3.2.6_pre20070714. target keywords are: "amd64 ppc ~mips sparc x86"
x86 stable
sparc stable.
