Debian DLA-1194-1 : libxml2 security update
High Nessus Plugin ID 104936
SynopsisThe remote Debian host is missing a security update.
DescriptionCVE-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.
CVE-2017-16932 parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities.
For Debian 7 'Wheezy', these problems have been fixed in version 2.8.0+dfsg1-7+wheezy11.
We recommend that you upgrade your libxml2 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
