Comment 4 Eike Rathke 2013-10-04 19:31:11 UTC
https://ssl.icu-project.org/trac/ticket/10318 results in
Error: Forbidden
TICKET_VIEW privileges are required to perform this operation on Ticket #10318

There is one commit assigned to that ticket, https://ssl.icu-project.org/trac/review/10318

I assume that is the only change required and it is applicable to ICU 50.

Comment 5 Vincent Danen 2013-10-04 22:09:14 UTC
Can't answer that one, as I don't have access to the ticket either, so I'm not sure whether that assumption is correct or not.

The following patch was applied to chromium to fix the issue:
https://src.chromium.org/viewvc/chrome/trunk/deps/third_party/icu46/source/i18n/csrucode.cpp?r1=219032&r2=219031&pathrev=219032

This corresponds to the following chromium security bug: (which is the same as the one linked in the CVE details in the description of this bug)
https://code.google.com/p/chromium/issues/detail?id=275803

Comparing the chromium patch with upstream patch (https://ssl.icu-project.org/trac/changeset/34076), i can conclude with significant confidence that the patch mentioned in comment #4 is the actual upstream patch.

Upstream patch: https://ssl.icu-project.org/trac/changeset/34076
