Comment 2 Huzaifa S. Sidhpurwala 2015-07-27 05:35:01 EDT

This is the same flaw was CVE-2015-2716 as documented in the Mozilla advisory at:
https://www.mozilla.org/en-US/security/advisories/mfsa2015-54/

However in chromium, libxml2 is used to parse XML web content, expat is used a dependency of libjingle and other associated libraries.
