CrOS: Vulnerability reported in dev-libs/libxml2

Project Member Reported by vomit.go...@appspot.gserviceaccount.com, Jan 6 2018 
Automated analysis has detected that the following third party packages have had vulnerabilities publicly reported. 

NOTE: There may be several bugs listed below - in almost all cases, all bugs can be quickly addressed by upgrading to the latest version of the package.

Package Name: dev-libs/libxml2
Package Version: [cpe:/a:xmlsoft:libxml2:2.9.4]

Advisory: CVE-2016-4483
  Details: https://vomit.googleplex.com/advisory?id=CVE/CVE-2016-4483
  CVSS severity score: 5/10.0
  Confidence: high
  Description:

The xmlBufAttrSerializeTxtContent function in xmlsave.c in libxml2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a non-UTF-8 attribute value, related to serialization.  NOTE: this vulnerability may be a duplicate of CVE-2016-3627.

joelhockey@ does it make sense to assign this to you? If yes, could you please take a look? Otherwise please let me know.

Also, I'm unsure why this has a separate issue from  issue 799707 . Should they be duplicates?

Labeling low severity because it doesn't list any uses for the vulnerability besides denial-of-services

I have made this a duplicate of  crbug.com/799707 .

This bug will be fixed next time someone does a roll from libxml.  Since this particular bug is not critical, and I have some outstanding patches with libxml, I'm planning to wait until my patches are taken by libxml before rolling.

as noted in the other issue:
Chrome OS system is already on libxml2-2.9.6, so this only impacts Chrome itself
