In addition, this update addresses a misapplied chunk for a patch released in version 2.8.0+dfsg1-7+wheezy1 (#762864), and a memory leak regression (#765770) introduced in version 2.8.0+dfsg1-7+nmu3.
For the stable distribution (wheezy), this problem has been fixed in version 2.8.0+dfsg1-7+wheezy2.
For the unstable distribution (sid), this problem has been fixed in version 2.9.2+dfsg1-1.
We recommend that you upgrade your libxml2 packages.");
