Package : libxml2
CVE ID : CVE-2017-0663 CVE-2017-7375 CVE-2017-7376 CVE-2017-9047
CVE-2017-9048 CVE-2017-9049 CVE-2017-9050
Debian Bug : 863018 863019 863021 863022 870865 870867 870870

Several vulnerabilities were discovered in libxml2, a library providing
support to read, modify and write XML and HTML files. A remote attacker
could provide a specially crafted XML or HTML file that, when processed
by an application using libxml2, would cause a denial-of-service against
the application, information leaks, or potentially, the execution of
arbitrary code with the privileges of the user running the application.

For the oldstable distribution (jessie), these problems have been fixed
in version 2.9.1+dfsg1-5+deb8u5.

For the stable distribution (stretch), these problems have been fixed in
version 2.9.4+dfsg1-2.2+deb9u1.

For the unstable distribution (sid), these problems have been fixed in
version 2.9.4+dfsg1-3.1.

We recommend that you upgrade your libxml2 packages.
