Hi All,

Saw this report about Charybdis and ircd-ratbox remote crash flaw at:

Researcher advisory suggests both the products are affected.

Sadly i could not get the contact details of either of the products
to copy on this email.

Should we be assigning CVEs to these issues?

This issue also effects =net-irc/shadowircd- , a fixed shadowircd is in the tree (6.3.3)

CVE-2012-6084 (
  modules/m_capab.c in (1) ircd-ratbox before 3.0.8 and (2) Charybdis before
  3.4.2 does not properly support capability negotiation during server
  handshakes, which allows remote attackers to cause a denial of service (NULL
  pointer dereference and daemon crash) via a malformed request.

Arches can go ahead and stabilise charybdis-3.4.2 ...I was going to file a STABLEREQ for 3.4.1 soon anyway.

GLSA vote: yes. 

I also vote that we combine this in the same GLSA as ShadowIRCd.
