A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or crash the application.

For the oldstable distribution (wheezy), these problems have been fixed in version 2.8.0+dfsg1-7+wheezy5.

For the stable distribution (jessie), these problems have been fixed in version 2.9.1+dfsg1-5+deb8u1.

For the testing distribution (stretch), these problems have been fixed in version 2.9.3+dfsg1-1 or earlier versions.

For the unstable distribution (sid), these problems have been fixed in version 2.9.3+dfsg1-1 or earlier versions.

We recommend that you upgrade your libxml2 packages.");
