$URL has an exploit for Opera 9.62 which allows for remote code execution by enticing a user to visit a malicious page. Might be Windows-only, I'm unable to even make opera crash (the page just sits there loading forever, Opera keeps responsive).
So.. waiting for new information / upstream reactions. No idea whether they've been contacted yet...

Btw, the segfault seems to suggest that an entirely unhardened Linux is coping quite well here - I see opera sucking up an enormous amount of memory and then segfaulting (probably some missing malloc check).
jer, could you also try remotely please? Maybe the "local" in milw0rm's title really means that the exploit code needs to be on the local machine already, which would make this issue much less important, imo.

Re-rating as B3.

I uploaded the code to dev.g.o/~jer/* and loaded that in Opera, but instead of the reproduceable segfault all I got was an idling page...
CVE-2008-5178 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-5178): Heap-based buffer overflow in Opera 9.62 on Windows allows remote attackers to execute arbitrary code via a long file:// URI.
opera-9.63 released, which fixes this issue along with others. Jeroen, please bump. No idea about CVEs except for the initial issue. Quoting the ChangeLog [1] * Manipulating text input contents can allow execution of arbitrary code, as reported by Red XIII [2] * HTML parsing flaw can cause Opera to execute arbitrary code, as reported by Alexios Fakos [3] * Long hostnames in file: URLs can cause execution of arbitrary code, as reported by Vitaly McLain. [4] * Script injection in feed preview can reveal contents of unrelated news feeds, as reported by David Bloom. [5] * Built-in XSLT templates can allow cross-site scripting, as reported by Robert Swiecki of the Google Security Team. [6] * Fixed an issue that could reveal random data, as reported by Matthew of Hispasec Sistemas. Details will be disclosed at a later date. * SVG images embedded using <img> tags can no longer execute Java or plugin content, suggested by Chris Evans.

It's in the tree alright.
Arches, please test and mark stable: =www-client/opera-9.63 Target keywords : "amd64 ppc x86"
amd64 stable
ppc stable
x86 stable, all arches done.
I've just discovered Opera 9.63 is now available for SPARC platforms. Could it be unmasked and tested as unstable?
GLSA request filed.
(In reply to comment #18) > I've just discovered Opera 9.63 is now available for SPARC platforms. Could it > be unmasked and tested as unstable? 1) That's not related to this bug and you ought to have filed a new bug report. 2) It's only available for solaris[1], which isn't supported in the Portage tree.

Neither the upstream advisory nor secunia say it's windows-only. Jer, could you please check whether we are affected by this one or not?
