Description GLSAMaker/CVETool Bot gentoo-dev 2017-11-24 12:54:51 UTC 
CVE-2017-16932 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-16932):
  parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in
  parameter entities.

CVE-2017-16931 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-16931):
  parser.c in libxml2 before 2.9.5 mishandles parameter-entity references
  because the NEXTL macro calls the xmlParserHandlePEReference function in the
  case of a '%' character in a DTD name.

@Maintainers libxml2-2.9.6 is already stable on some arches, please confirm if we can stabilize it and clean previous versions.

Thank you

2.9.6 is ok to go stable for remaining arches.

GLSA Vote: No
