Red Hat bug mentioned in URL field now contains:
"Upstream patch:
http://bugs.icu-project.org/trac/changeset/29356"

So bug #437834 was fixed since ICU 4.6.1.

Thank you, Arfrever. 

GLSA vote: no. Not only would this lead to a client-side DoS, but ICU users should already be protected by applying the resolution in GLSA 201209-07.
