Comment 1 Jan Lieskovsky 2013-03-05 10:55:14 EST

Created icu tracking bugs for this issue

Affects: fedora-all [bug 918168]

Comment 3 Huzaifa S. Sidhpurwala 2013-03-11 00:36:26 EDT

Analyzing the issue, the maximum impact seems to be DoS, it is not exploitable.

Statement:

This issue affects the version of icu as shipped with Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this issue as having moderate security impact, a future update may address this flaw.
