CVE-2009-1885 xerces-c, xerces-c27: Stack overflow when parsing recursive XML structures
Last modified: 2014-12-02 04:13:45 EST

We actually do want to keep this open for bit longer, as xerces-c is shipped as part of some products, but due to the impact of the flaw itself and impact on particular product, updates are not expected to go out immediately. So I will re-open, feel free to un-CC yourself, as all you care about is fixed by now. Thank you!
Ok, understood. Feel free to do everything you need with this ticket :)
