CVE-2009-1234 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1234): Opera 9.64 allows remote attackers to cause a denial of service (application crash) via an XML document containing a long series of start-tags with no corresponding end-tags.
This might be considered a non-issue if it just causes opera to crash...
Seems to be fixed in 10.0 which is already stabilized.
A request is in for bug 264831, so this can easily be included. I vote YES.
Yes, too. (You meant #283391, this is #264831)
