Google Chrome bug is: https://code.google.com/p/chromium/issues/detail?id=422824 However, the bug is currently not public. However, the following commit can be identified using the bug id: https://chromium.googlesource.com/chromium/deps/icu/+/3af4ce5982311035e5f36803d547c0befa576c8c It covers two Chrome bugs, the other one is associated with CVE-2014-7923 also fixed in Chrome 40.0.2214.91. The commit references ICU upstream bugs, which are also currently non-public. ICU bug and commit links follow: http://bugs.icu-project.org/trac/ticket/11369 http://bugs.icu-project.org/trac/changeset/36727 "Regex, fix incorrect optimization of patterns with a zero length quantifier {0}" http://bugs.icu-project.org/trac/ticket/11370 http://bugs.icu-project.org/trac/changeset/36724 "Regex, add missing range check of length of a look-behind expression." I do not currently see any information that would allow mapping the two ICU changes to Google Chrome CVEs. This issue has been addressed in the following products: Supplementary for Red Hat Enterprise Linux 6 Via RHSA-2015:0093 https://rhn.redhat.com/errata/RHSA-2015-0093.html (In reply to Tomas Hoger from comment #2) > Google Chrome bug is: > > https://code.google.com/p/chromium/issues/detail?id=422824 > As per the chrome bug, this was fixed upstream via: http://bugs.icu-project.org/trac/ticket/11369 http://bugs.icu-project.org/trac/changeset/36727 "Regex, fix incorrect optimization of patterns with a zero length quantifier {0}" Created mingw-icu tracking bugs for this issue: Affects: fedora-all [bug 1190132] Affects: epel-7 [bug 1190133] Created icu tracking bugs for this issue: Affects: fedora-all [bug 1190131] icu-50.1.2-12.fc20 has been pushed to the Fedora 20 stable repository.
